Hi Michael,
sorry for late reaction. It is not clear from your review whether you have been using Cleanup or Avast Mobile Security(AMS), could you clarify? Thing is that in AMS there is provided only a fragment of Cleanup features.
It’d be useful if you can please share with us GUID (unique user identifier). It can be found in Cleanup on “About screen”, you need to tap 5 times on app version and you get to hidden page where GUID can be found. Tapping it copies that code to clipboard.
Please also ad an information what exactly have you been deleting. It could help us to remove the problem.
Thank you very much!
