Bug: Can't login on mobile website

I wanted to submit a bug for the app, which I usually use on mobile. I tried to log in on the mobile website, but the log in button doesn't seem to work at all.

I tried in Safari (iOS 26.5) and Chrome for iOS (up to date, v149.0.7827.137). Both app had similar behavior that made it hard to see the password box and even when it was available and filled in, the log in button did not appear to do anything.
