We are having a similar problem. Plus there is no server-to-server notification on the purchase after expiration. Apple, what is going on?

We are having the same problem. We've noticed two other strange and new behaviors. We get no S2SN on the resubscribe after an expiration. On renewal messages receive both the original transaction and the renewal transaction. We used to receive only the renewal.

Same issue too.

I'm interested in this too. One thing we've tried (unsuccessfully) is to export real health data from a beta tester's phone and import that data into a test phone. There were several apps that claim to be able to import apple health data (export is a feature of Apple Health already), but none of the apps worked.
