Recently we are seeing 502 errors on the receipt validating API, documented here: https://developer.apple.com/documentation/appstorereceipts/verify-receipt

Has anyone else seen problems like these recently?
We are planning to move to the newer (non-deprecated) APIs, but are expecting that to take "a minute".
