In my case is not renewing the subscriptions, I am validating the receipt on device, not sure what is happening.

To solve this you just need to change your Mac Language

Hi! I had same issue but in my case was for Paid Apps Agreement, I contacted Apple Support by email and they answer me in two business days, after that, I was able to see and accept the new agreement on Appstore Connect. Hope you can fix this soon. Cheers, Fernando E.
