On my iPad, I am prompted for my 1P password in Safari almost every time I go to Sharing and select the 1P app. I have autolock set for 30 minutes, but I am usually prompted for my password even if I immediately return to 1P. I tried opening the 1P app and leaving it open, then returning to Safari to see if that would help, but that made it worse. I mostly got the error message "Error Loading one password extension" but occasionally 1P would correctly load without re-requesting a password.
I had the PIN Code option in 1P disabled, so I enabled it but the results were the same.
