When creating a MP listing, and the file size is over 1mb, it says it can’t be uploaded, but then you can’t re-upload it, as the upload button vanishes. Unless you refresh the page and lose everything, or save it without a photo, then open the listing again, scroll down and try to upload it again.
I wish it would say failed - please decrease your file size with a (upload button), so we don’t have to refresh or leave the page.
