I’m trying to upload a background that I made, but every time I try nothing happens. I open my photos, click the one I want then nothing happens. Does anyone know how to fix this? Has this happened to anyone else? If needed, I can take a video. Thanks!
Possibly because it isn’t the right length/width, you need to adjust the photo to meet the minimum and maximum l/w for a background.
No, I don’t think that’s the issue because the background I made is the exact size needed. Thanks for helping, though!
It could be a bug related to your browser or PC. I myself have experienced this on some websites when selecting images from my disk. What I usually did then was either restart my browser or PC and then it worked again. 
Thank you! I will try this.
I had the same issue . I found out it was because I didn’t save it with the size in the name. Try doing BACKGROUND1920x1136
