I recently installed GOS and when I tried the banking apps for DKB (Tan2Go) and Sparkasse (S-PushTan) from Germany they worked, though I had to wait for the verification letters to actually use them. Now (yesterday I think) GOS did an update and the apps don't work anymore. They're just stuck on the splash screen. I've tried deleting their cache and reinstalling them, but nothing changed.
These apps are installed via Google in Sandbox Mode.
