I haven't used it outside of Windows Firefox and Android but it works great for me as well.
For mobile specifically: Rarely do I have any issues, and when I do, I have a quick panel button for Bitwarden (top drag down menu) that lets me manually trigger it. I can't think of any apps that it doesn't work with. My one nit is that autofill credit card info doesn't work often, but obv that's a secondary use, and the info is still with me if I ever need it on the go. And adding new login info can be a little tedious on mobile – much easier to create it first, then autofill. Highly appreciate the 2FA feature too. The auto copy feature feels really seamless regardless of if I'm on my phone or not.
I'd be curious what issues you seem to be running into with it.
I'm so happy people still know this movie.
