I'm not really asking for support but I'll put this topic here in case anyone thinks of something or just let's me know it's not possible. Here we go:
I changed to a phone provider and received a Chromebook as an incentive. I'm really enjoying using it even though it's so Google-centric. However, one thing is quite annoying. When I try to log into my Gmail account using the Brave browser, it won't let me (see attachment for error message).
I've never had this problem on my PC using Brave so I can only think that Google doesn't like me using a browser other than their built-in Chrome browser. The only workaround is to use their browser or the Gmail app.
If Google is doing this, they're definitely acting evil. Unless there is something wrong in the Brave app, there's no reason why it shouldn't work.
