I have an update of an app which has an auto renewable subscription. When testing locally, everything works fine with the sandbox url to verifyReceipt (especially the auto renewals). When testing with TestFlight: I use the same sandbox user. The monthly app subscription is only valid for 5 minutes (same as locally) and: The subscription is not renewed. Is this a known issue? Or is there some "magic" trigger to really use the path to first test productive url and afterwards sandbox as stated verifyReceipt - https://developer.apple.com/documentation/appstorereceipts/verifyreceipt. I am quite sure that the expiration date is not updated, but will debug further.
