I have a Samsung A12, and it's the only device of mine that seems to be having this problem. When I click "Drop Image" and it takes me to where it should, it doesn't show any of the pictures, just dark gray squares where the pictures should be. I click on where the picture that I want should be, the picture will upload with no problem. It's just I can't see the pictures in the Drop Image section. I have restarted my device recently, and it's still not working correctly.
