Hey. I sent itch support an email about this a week ago (ticket #255522) and didn't get any response, so I'll try here?
When I first released my asset pack, the payout was coming out to around 83% of the gross revenue. That makes sense to me--itch gets its 10% cut of a $12 pack, then Stripe/Paypal take somewhere around $0.72, plus a flat one-time $3 for the tax interview, straightforward enough.
But as soon as I attached my Paypal account, that payout immediately dropped to around 64%, with future sales from that point forward also now returning a little less than 2/3rds of my gross revenue. I'm based in the US and don't understand why that much would suddenly be withheld. What happened?
