Wonder if anyone can help - Checked my activity log and its come up with a message saying Avast Account disconnected !! its says you have lost the possibility to see devicedetails in my avast.com portal !! what does that even mean
I have uninstalled and reinstalled but it did it again this morning
It means that you signed out of the app with your email address (the one that is connected to your Avast Account).
The app will still work since you are connected via your activation code.
There are different ways to activate your Avast Mobile Security subscription.
Please see this guide for more information: https://support.avast.com/en-ww/article/Activate-Mobile-Security/
