FYI ... Not a biggie. Just got notified of 1Password Beta 3 update and the updater informed me that it found multiple copies of 1Password.app (all within Time Machine Backups). I'm also running the public beta of Big Sur and also converted Time Machine to backup to an APFS formatted backup drive. I assume since I never got this before I converted Time Machine to APFS that this is the issue?
