How long does a pending purchase in Apple TV take to be processed?

I rented Project Hail Mary from Apple TV three days ago. Turns out that Apple TV can't stream to my Hisense TV because VIDAA, like Google TV and Android TV, have payment complications that has resulted in some TVs not being eligible to receive streaming. This was not printed clearly anywhere that could be found quickly. No, it took over an hour to find the information. I would therefore like to get a refund for the rental (I know it's not much but Apple is not short on money). I can't request that yet because the payment is still in "pending" status. It needs to be a completed transaction before I can start the refund process. How long does it take for the pending status for a transaction take to convert to a completed transaction when buying/renting from Apple TV?
