Google accounts in blog comments
I have a Blogger blog which uses a custom domain.
When I attempt to reply to a comment Vivaldi does not auto detect my Google profile & if I select "use Google profile" the comment is not posted.
This works perfectly in both Chromium & Firefox.
Perhaps you need to activate Third Party Cookies in Vivaldi Setttings → Privacy or unblock some cookie domains?
Allowed third party cookies and that worked. Thanks.
