Ditto: App Locking not working whatsoever except for PIN entry into Avast app. This is the Premium $14.95/yr paid version. Running CyanogenMod 12.1 (latest nightly) (ie. Lollipop 5.1.1) on Samsung Galaxy S4 (T-Mobile SGH-M919).
Btw, thanks but no thanks for offer of free beta tester.
I will notify Google Play Store about this issue. Imho, you should post a notice of deficiency on the Play Store offer until this is cleared up.
Not a happy camper about all this.
