Grant Access in Poweramp v2 Discussion (Legacy Version ONLY) Posted March 9, 2015 I've resolved the issue (for my phone at least). I managed to get the 'Grant Access' dialogue to appear by deleting a file. Editing the Info/Tags of a file would not bring up this dialogue. I'm using Poweramp 573 on a HTC One M8 with Android 5.0.1. It works, great .
