I’ve been trying to submit an asset on the fab marketplace, now the asset says “Changes Needed”, but I didn’t receive any email or any suggestion on what are the changes i need to make.
Epic/Fab just won’t help on many cases like this one and don’t reply to support requests. I hope in your case they do take time to look into it. Similar issues have been persistent for months and they don’t bother fixing them. You could consider making a new duplicate and submitting the same asset again.
