Bug description

When trying to type in the recovery key for a backup made with my desktop app, I can't type in the # character (number sign, hash, the pound sign) into the "Recovery key" text field. My key contains a # character so I'm unable to restore from backup :(

Just want to confirm this also is an issue with the 8.12.1 beta version.

Wow, I just replaced the # with O and it worked. There's definitely some UI issue with showing and copying the code with the # but not being able to paste it into the Android recovery field.

This should be fixed in 8.11 (10b0221)

I replaced the # with o and the = with 0 and it worked. This is on 8.10.3.
