Chrome Protection Disabled... But it's not!

I keep getting a message to say, “Chrome Protection Disabled.” I’ve tried to follow the instructions to re-enable but it is already enabled. I have switched off and back on but still get the message. Next I tried switching off Chrome Protection and then the device. Then I turned the device back on and enabled Chrome Protection but still get the message.

Any other ideas for a fix would be welcome please.

I have a Samsung Galaxy Tab S3 running Android v 7.0 and using Avast Mobile Security v 6.8.3.

Hi, it seems something keeps killing our app in the background - when it happens, Avast loses “Accessibility permission”, which makes the Chrome protection stop working. You are probably using some power saving mode or a task killer app, or you have disabled the Avast Permanent Notification (in Settings > Notifications).
