I am licensed owner of Poweramp and having problems using Poweramp in places where there is no network. Application don't want to work in offline mode without checking licence. Here is an answer of support team: To resolve this issue: 1. uninstall Poweramp Full Version Unlocker 2. ensure you have internet connection on the device up and stable 3. install Poweramp Full Version Unlocker from Google Play Store app. Reinstalls to the same account are free. Installing Unlocker from APK won't resolve the issue 4. You may need start/wait a bit/exit Poweramp 2 times to reload license state. This works, but in a two weeks i run into the same issue again, is there any way to get rid of this annoying checks?
