In 2017 & 2018 I purchased 6 licences for my various devices. In the last few months I receive the following messages: Failed to Validate "No such Google or Email (Android 3.0) account registered on device." I would like to use Poweramp on this device. It has all the music of particular genre on it. There is no Google email registered on this device that fits the registration. Most of my registrations were not gmail addresses. How do I activate the licence for this device? Thanks.
