Unity IAP doest initialize on IOS 13.
My game has been rejected 3 time with the same issue. IOS resolution center says "We found that your in-app purchase products exhibited one or more bugs when reviewed on iPad and iPhone running iOS 13.5.1 on Wi-Fi." I have no idea what the problem is. In app purchase works fine on device with IOS 12.
