Hello,
i am very sorry to inform you that we have a problem in AMS regarding Premium licenses. If you have installed on your device any of the following products:
-Avast Mobile Backup,
-Avast Anti-Theft,
-Avast SecureLine,
you can be experiencing problems with either purchase or refresh of your Premium license. The problem is caused by shared files of these applications. You should be able to fix it by:
1)Uninstallation of mentioned Avast apps (Mobile Backup, Anti-Theft, SecureLine).
2)Running Avast Mobile Security and either refresh your license by "GO PREMIUM" button, or insert voucher. Now AMS should properly reflect that you have a Premium license.
3)Install the apps you uninstalled in step 1) and set them up again.
We are very sorry this has happened and we are working on an hot-fix, which should go fully live next week. If you purchased Premium license and you were not able to refresh it the way described here, please file a ticket to Avast support.
