After the last update of virus definition the version number is 180521-06 and the date is (31 of December of 2013), because of that I believe that the avast can’t stop notify that I have a problem unsolved and I need to update, but I can’t because that is the last version
I have the ame problem, I have avast premium account on my both phones (Galaxy S7 and Moto e4plus), also we have another tow mobile devices at home with free avast and all experienced the same issue.
I had the same issue too. I deleted and reinstalled the app to my Nokia 3, now with latest updates, but unable to connect it to my account, it keeps saying ‘Authorization failed. Sorry’
yet I enter the same password to get into the avast website online.
