Discord profile picture not setting on Mobile

Whenever I select an image from my phone gallery and try to set it as my profile picture, nothing happens. My previous profile picture stays the same. I've tried a solution, which is cropping the photo I want as my profile picture, but it didn't work. I can only set my profile picture on desktop, but my phone gallery isn't on there, and I don't know how to transfer photos to a desktop. I need solutions, how do I fix this?
