(TURN OFFFFFFFFF) Show Button Shapes
N it should work perfectly now....
I'm having problems with s10 plus with my paid themes, wallpapers and icon packs. I keep having to download them all again everday. Same is happening on s9 plus. I don't know what's causing it. Do you or anyone else have these problems? Any idea on how to fix this? I' keep having to go into galaxy themes app and clearing cache. It works for an hour then problem starts over again.
