I noticed an annoying issue since several weeks now. 1Password on my Mac is configured to request the Master Password every 2 weeks. Nevertheless, it asks for the Master Password several times a day.
I never use the lock feature in 1Password, I just let it lock itself when the MacBook is inactive.
Funny thing is, when this happens, I just close the application and re-open it, and then I am able to use TouchID without entering the Master Password.
I have applied the latest update that came yesterday, and the problem is still there.
1Password Version: 6.8.2
Extension Version: Not Provided
OS Version: OSX 10.12.6
Sync Type: Dropbox
