Arlo Android app - fingerprint Log-in on S7 Edge / session expired

[toreador]

Hi

I'm using the fingerprint log-in option on the Arlo app for android (using an Galaxy S7 Edge).
After some days I've got the message upon trying to log-in, that the (fingerprint) session has expired and I that I have to reenter the password.
How can I change this behaviour? I never ever want to have to enter the password on my phone again.
It should always work via fingerprint without expiring.

Thanks in advance

Occasionally when this happens to me on my S7E, I force close the app and then when I reopen the app, it's back to not needing a password

Thanks, will try it next time it happens.
