Hello, the first time I uploaded a background image to our team it loaded fine , but now any image I try to add never works, shows the uploading background then goes back to the first one that did work.

I tried using one of the provided bg's and does work , but when ever I try a new one of my own that's under 250kb it just goes back to the first custom I used, by the way is there a size l/w restriction ?

If the image was too big; you'd get an error message - 'Maximum image size exceeded'.

Usually it takes some time for the new image to show up when uploading an image over a preexisting one.

The old image would show up again but the actual image will take some a while to show.

Sometimes it takes a few hours for the 'actual image' that you uploaded to show up.
