I'm working on a seasonal avatar for another user and I'm having a hard time providing a version/size they can successfully upload. These are the various sizes. I tried swapping out my avatar for these and they ran. Any sage advice and/or wisdom? Pepsi is using a phone to upload the file, but I don't know why that would make a difference, the animation doesn't run when she uploads the file as an avatar. I looked at the Xenforo support forum but came away even more confused.
