No I don't see the SD card and can't select from internal storage. How does one go about "clearing Poweramp data"? Do you mean a full rescan? I've done 3 reinstalls. I've been through everything. Poweramp is the only app of many including a number of music/media players that won't read the sd card. It's not an android problem, PA works fine on my phone, it's a chromeos problem on a Samsung galaxy tablet. If you have access to a chrome tablet and sd card try it yourself. It's a bug my friend.
