Reliable calendar provider with two-way sync and Android support

Hi and yes, Google and Microsoft do all to exclude others.
I used a Freenet mail address for my Vivaldi account as recovery mail but I use the Vivaldi.net account address in OneCalendar.
I am sorry but I cant help with two step authentication, I don't use this.
@Dancer18
Does aCalendar+ support CalDav and two step authentication or do you use a third party CalDav app?

Cheers, mib

I use DAVx5 that is working fine from the beginning, easy to use, also with sync of contacts and tasks.

Ok, so can you please advise how exactly did you connect your Vivaldi.net account to OneCalendar on Android? I can't seem to be able to just enter my Vivaldi.net password when setting up a CalDev calendar. It requires some "app-dedicated password" or something. But when I enter the 2FA password generated in the Vivaldi account (on this website here), it doesn't work either. So I'm not sure what I'm doing wrong. Could a staff member help perhaps?

Just wasted an hour setting up everything through iCloud, and apparently Vivaldi duplicates iCloud events as well. If the duplication bug exists with a Vivaldi.net calendar, I'll have to give up on Vivaldi altogether, with deep regret, as nothing else matches the awesomeness of its UI.

@Ekhangel
I hope one of the mail developer steps by.
As I mention, username, password, server with no two factor authentification.
By the way iCloud does the same as the others, they doesn't care about standards, they create there own.

The duplication bugs are tackled from the team, some are already fixed in the snapshot, some internal but not published yet.

When I try that it says "Invalid URI: The format of the URI could not be determined".

No idea what "URI" is.

EDIT: Ok, I got past that – now it says "CalDAV error when adding account: Not authorized", and then it says "if you are using two-factor authentication, you must generate an app-specific password for the app".

Ok, just gave Vivaldi.net a shot in Vivaldi Calendar, and the duplication bug is also there. So, that's a lot of time wasted for nothing. A bit disappointing. I do hope the fixes/patches come about soon though (a word from the devs on this would be much appreciated). Before that happens, I'll have to move elsewhere. Luckily, we still have Gmail / Exchange...

@Ekhangel
Where do you get a duplicate?
I created an event in the internal Vivaldi calendar client a few minutes ago, no duplicates in the web client and in OneCalendar.

Ekhangel

In the Vivaldi Calendar (for Windows) only. Not sure why I'm getting the duplicates. The problem began some two weeks after beginning to use the app, initially it was all fine. And there were no updates inbetween (I guess). So not sure what's the problem. But judging from historical posts in these forums, I'm not the only one.

@Ekhangel
Hm, is this a daily event?
I will check on Windows.
EDIT:
Same on Windows 11, Vivaldi 6.6.3271.50.

Cheers, mib

Ekhangel

Well, it's an even with specified time, yes.

mib2berlin

@Ekhangel
Hm, I cant reproduce it.
We have a report if a user create an event, sync it and then change it to a daily event, the move it one day ... a few steps more.
Very hard to reproduce.

VB-104869
[Calendar] Event exception duplicates

We need other user can reproduce this on Vivaldi 6.6.3271.50.

Ekhangel

Well, good luck. I'll stick with the good ol' Calendar App from Windows 8 till then. And when it's withdrawn (supposedly this year), I don't know what I'll do, because everything else is utter crap, one way or another.

@Ekhangel I am sorry for your frustrating experience with Vivaldi Calendar.

We have had issues with duplication of events for a long time which have mostly been related to recurring events and usually google calendar. Sadly there was a regression that got released with version 6.6 of Vivaldi which makes duplication much more common and not limited to recurring events. It still doesn't happen all the time and we don't really know what triggers it.
The problem has already been fixed in our development branch but due to some conflicting changes it could not be included in minor update released yesterday. Not sure if we will try to take another attempt at backporting the fix or not. Worst case it will be fixed in next version.

Positive from this is that we have located some more possible sources of event duplication so the long standing problems with them might be improved.

eggert

And BTW for those affected by this recent bug where events created in Vivaldi duplicate on next sync with server, it should be fine to delete the first event in Vivaldi. The first event, the one with the broken info causing the duplication, will be shown at the top or to the left of the duplicated pair. Alternatively if you can live with the duplication, it will be cleaned up automatically with next version of Vivaldi.

Ekhangel

Thanks a lot for the news. Any details on when is the next version coming?

Or, perhaps, could I try out some legacy releases, if available?

@Ekhangel
Hi, you can check the snapshot builds, they are for testing bug fixes before they get into stable.
Don't install it over your existing stable, you cant go back, use standalone install.

@mib2berlin Thanks!

Sorry for the late response but I just wanted to post the update that a proposed fix for this was released in a minor update to stable last Friday, April 12th. Version number is 6.6.3271.61.

Although we still know that there can be duplications in some cases which we haven't been able to pinpoint but that is much much rarer. I sincerely hope that this update will fix the regression of 6.6.

@eggert

I can officially proclaim the issue resolved – at least on my end. Thanks a lot for your work, the calendar is great! Cool visuals and great functionality.

Were it not for Vivaldi, I have no idea what I would move to after Microsoft has virtually abandoned its Win 8 Calendar, because everything else sucks bad.
