I have bought Poweramp for about 2 years. And now, when I change my phone, to oneplus 5 it cannot verify the license.I dont know if this is a bug of the alpha version or not. What I have done are: Un, then reinstall the program several times. Clear data and cache, then rerun Uninstall, then clear data of Playstore, then rerun and reinstall Nothing works, and it said that license verification failed, reason unknown/unknown. I have installed Poweramp on another phone, with my gg acount, it works. So, could anybody help me to find out what is the problem here?
