so it seems I have a little problem and i don't know where it came from but I will try to describe.
Yesterday everything was working fine, so I started PocketCast to refresh my Podcasts and it tried to download a new one which had 1,6GB. The SDCard did not have enough space left so the download did not start.
Since then I had the download-symbol in the notification bar but i did not really care.
So, today i wanted to watch my photos with the galery App and none of the photos on the sd card showed up. Same in the Apollo Player, no Songs are shown. So I checked the SD Card and everything is there.
My next step was a complete wipe but this also did not help.
Anyone any idea?
TL;DR Download did not work, since then apps don't see any Media Files on SD Card
