Hello. I'm having trouble adding an avatar. I click on the prompt to edit avatar but it loads a blank screen. I'm on an android device. What am I doing wrong?

The blank screen is not centered, I'm on a kindle and can barely see the upload button, Idk if you can scroll over to be able to see it or not. I don't think you're doing anything wrong, either scroll over or pinch the screen smaller maybe. Hope it works for you.
