Asana attachments not working

Awoodstock

Hello, I've been recently using Asana and I normally attach Google Drive documents/slides/etc when I create a Task. To do that, it asks you to sign in to your Google account, it displays the folders and documents, and you can choose from a list. The problem is I can't do that on Vivaldi, a pop up shows, I write my e-mail and password for my G account, but then I get an error message:

Then, when I click on sign in (to sign in again), this message shows up:

It works on Safari and Firefox, so it is not a problem with Asana. Has anyone else experienced this? I already disabled the tracker blocker and allowed cookies.

MacOS Big Sur 11.1/Catalina 10.5.7
Macbook Air 13" 2017/Macbook Pro 15" 2015
Vivaldi 3.6.2165.34 (Stable channel) (x86_64)

Thanks!

In case anyone experiences a similar problem, I just fixed it this way:

Open: chrome://settings/content/cookies
Add the following URL to the Allowed list: [*.]google.com

I had already added accounts.google.com but it still wasn't working.

Hope this helps, if needed.
