Many users reported that their playback may stop after some minutes. Most common reason is system battery optimization. Please try following steps:

Firstly, please click “rescan library” menu item from toolbar to rescan device. You can refer to music library refresh section for more info.

Please launch paid version first before you uninstall free version. When first time you launch the paid version, it will try to migrate some data from your free version, such as your favorite songs list, playback history, etc. After the initialization of the paid version, you can safely uninstall the free version.

There is a big floating shuffle button in each detail page to play songs in shuffle mode. If you want to play the songs in sequence, just click the first song in the page, please turn off shuffle in playing page, or disable "keep shuffle mode" in settings page in this case.

No. You can safely uninstall free version and only keep the paid version. They are two independent apps.
