I know it’s a problem on Epic’s end
I bought more 100 assets including your and It is not the first time that I have problems with this marketplace (some still open for weeks)
But there are a lot of things can not be justified especially for recharge on the price, these include slow updates end super slow email support…
I recommend you going on Gumroad or Sellfy also.
I prefer to shop elsewhere for NOW, especially 3d models, saving time and money
