I´ve been using Poweramp for more than 3 years without any problems on my Fiio M11. But now in release 922-925 every time when I launch Poweramp it does a full rescan of the library. It seems to loose all its data every time it is shut down or the Fiio is turned off. I have more than 22.000 tiles on my 2 sd cards so the rescan takes a lot of time. Does anyone have a solution for my problem?
