Please allow PIN unlock in 1P8 Android

Has there been any further progress on adding support for unlocking with a PIN with 1Password 8 for Android? Having to regularly unlock with a password really degrades the user experience. I have recently moved from 1Password 8 for iPhone which supports unlocking with a PIN and the user experience is much smoother. I would rather use unlocking with a PIN than biometrics though I can't see that unlocking using biometrics is supported either with 1Password 8 for Android. Another option is to allow permanent unlocking of 1Password and let the user rely on the phone's PIN for data protection though the ability to always be able to unlock 1Password with a PIN is the preferred methodology.
