Thanks for getting back to me. I confirm that I made two purchases with two different amounts that should add up to more than $10. Is the option only available if you have made a single purchase on itch.io of $10 or more?
I believe it’s because you bought the item 3 years ago under a different email, so although your account “owns” the purchase, it did not “buy” it. I’ve attached it do your account so you should be within the threshold now.
