It's a week that I try to install v2 or v3 with or without a connection, uninstalling and reinstalling, but the error is still the same APM response answers me - 500_NO_ORDER_FOR_ACT myemail.it
I also went to the Poweramp forum, but they make it as easy as you do, it doesn't work for me!
I don't know why, I checked and double-checked the data, but they are correct and correspond to those sent to me by PayPro.
Personally I'm a little fed up, I bought the license via Paypal, I opened a dispute, I hope to recover the money.
I will have to settle for the FiiO Music player, of which I hate the lack of fade between the songs, at least in the version on the M6!
