I’m on an M1 MacBook Air. OS is up to date Monterey. Not self hosting (not even sure what that is).
As I say, it loads fine with the same login on the other browsers, so this is very odd.
Another thing I notice is that logging in with biometrics does not work on Firefox, even though I have selected the option and confirmed in the desktop app. It works in Chrome and Safari. Also, when I login it takes up to 5 seconds to load the data, which is kind of slow. Is that normal?
I guess a lot of odd little issues for me.
