Unable to set profile picture

I tried to change it, but got the error “either too large or not an avatar”. When I tried to change it back to the picture I’ve used for months, it said the same thing.

I’m getting this problem as wel

What is the resolution of the image you are attempting to change to?

My old one was 802x859

It has never worked well if you’re uploading it. Best thing to do is use a direct image link hosted from somewhere else.
