My app has been rejected 4 times now with that same message from App Review: Prices not showing up on iPad with iOS 14.4 on Wi-Fi. No clue what to do. I keep asking for a log of what they see but have been getting ignored. I'm using Unity IAP with local Receipt Validation implemented. If anyone here reports having this same issue and are not using Unity IAP, please do mention. This would help me confirm that the issue is not specific with Unity.

I've been rejected 5 times now with this same problem. Everything works in Testflight: prices show up, buttons are active, receipt validation works and transactions succeed. But when I submit to App Review, They always reject with the following message: "We found that your in-app purchase products exhibited one or more bugs when reviewed on iPad running iOS 14.4 on Wi-Fi. Specifically, your app’s In-App Purchases have no price. Also, upon further review, your app’s Buy button is unresponsive."
