Heya,
It's my understanding that paid games can take a little while longer to be approved and indexed, especially if it's an account's first paid title. I don't believe they work on weekends either and the estimated timeframe is more for business days, so I'd say to wait an extra week or two before getting worried! Also, a lot of the estimations they have on their FAQs and such are perhaps a touch outdated and as itch.io has grown, I believe it's been taking a tiny bit longer for them to catch up on everything.
