I just tried this on Android from F-Droid. I couldn't get past the login page, unfortunately. Bitwarden popped up to auto fill the form, but it didn't work. I tried typing my credentials manually, but it was rough because of the weird quirks with the text boxes. Why does the carat jump to the last character after every keypress? It made it nearly impossible for me to correct a typo. My password is pretty long, which royally confused the password input field. After a certain number of characters, it just stopped displaying anything. It also does not respect my system preference of not displaying the most recently typed character unmasked. Finally, after all that, I clicked login and the button just changed to a spinner forever.

I realize this is alpha quality software, but to claim to be focused on user experience and have such horrible UI issues does not give me any confidence, sadly.
