I'm not sure what's happening here, but your account does have a Premium subscription. Are you saying you don't see the option to turn on Face / Touch ID unlock in mSecure's Settings on any of your devices? Should see that option as long as you signed in to the correct account.

There is No option to unlock with Face ID or Touch ID?
I have several devices with mSecure on it that work with Face ID or touch ID but I have a new iPad 10th generation where it does not have the option to unlock with either of those
