1Password extension for Edge extremely slow

I have the same problem. The extension becomes completely unusable (hangs forever or displays a message about a database error) and often forgets my account completely, meaning I have to completely re-set-up the extension.

To add insult to injury, every time I do log in to the extension again, I get an email about a new login...

I'm using Brave if that helps. (I've disabled Brave Shields for my.1password.com, although I doubt that matters because my account there seems to stay logged in just fine.)
