Anti-theft portion of Mobile Security not working on Android 8

[REDACTED]

All of my devices which have android 5, 6, etc. have a properly functioning anti-theft. However my new device which has android 8 does not work correctly with the anti-theft. The anti-theft thinks that it successfully locked my device. However the device does not show the avast lock screen and instead just goes back to the normal lock screen which is swipe to unlock. So the lock really does nothing on the device.

I think it might somehow be related to the screen lock settings on the device which all say "because you've turned on an accessibility service, your device won't use your screen lock to enhance data encryption".
 
But for whatever reason, anti-theft locking does not work on my android 8 device.

I am having the exact same issue on two Android devices. After locking the device on the Avast portal, I only get the Android notification screen with swipe to unlock, which then opens to the Android lock screen. The Avast screen with the optional message and contact information never shows up until I unlock the device at the Android screen.
Both devices are running Android 8.0.0. One is a Samsung S9 and the other is a LG V30.

Gerry and Corey: thanks for reporting the issue, it has been a known one and should already be fixed in the latest Beta. If you are interested in becoming a Beta tester, please read the FAQ article: https://goo.gl/r8UPdZ, otherwise please wait for the public release (December).

Marylin: I am afraid I do not fully understand - could you specify the problem? Is the Avast app turning off by itself?
