Hello,
I am using the paid version 2.010-build-588-play of Poweramp on an Ulefone Paris
with Android 6 MM.
Previously I used a different phone with Android 5.1.
I reinstalled the Poweramp app and the Poweramp unlocker and verified my purchase.
So far so good.
I tried to convince Poweramp to scan the internal and the "external" SD card memory
but the program refuses to recognize neeither the internal nor the external memory.
The built in music player has no problem whatsoever.
Additionally, everytime when I start up my phone in the morning Poweramp comes up
with the "testversion will expire blabla". So it is also unable to "write" the
verified license to some memory.
And yes, the program has write access to the telephone as well as the memory.
And no, the SD card is not as adoptable storage configured just as mass storage,
anyway the issue is with the internal memory too.
I guess it has something to do how Google has changed the access to the sd cards
in MM again but I can´t change anything about that.
So hopefully you can fix something on the app side.
I will try other music players to see how they work and post the results.
Regards
