Not sure if this belongs here, but there is no email on the website for support. I tried to submit something through the app and it wouldn't do anything. So, I'm assuming this is a server glitch on Poweramp's end. If it's not It's a back handed attempt to make me repurchase something I have already paid for. So what gives? Whats the problem. I have only installed it my own devices on the same wifi network! I tried downgrading the latest version ( v3 build-841) and it still gives the error. This was a website purchase for a while ago. You guys really need to provide email address support if your going to accept purchases outside of Google Play Store.
