Not only do I have an issue with files not appearing in Poweramp, while they are on the external SD card, it appears that Poweramp is deleting files. I have 232 folders containing 1,003 flac files. All of this is approximately 28GB is size. When I load the SD card, the file browser sees all of the files and their directories. After rebooting the the phone, the files still remain so that would tell me that the file system is not deleting them. I then ask Poweramp to scan the folder -- and only that folder. The GUI states that it is scanning the directories and then appears to "hang". Poweramp appears to runs for at least the display timeout and then Poweramp seems to finish. When I look at the SD card, around 900 of the 1003 files are gone -- just plain gone. The space occupied by the files is freed and available for the SD card to fill. I have purchased the product and download the latest version on the Android app site. I have de-installed, re-installed, rebooted, reloaded the SD with all of the flac files, and the result is basically the same. It is not always 900 files, sometimes there are more missing, and other times there are more. However the end result is the same -- Poweramp appears to delete the files.
