If you have a lot of purchases, your old transactions are truncated in the sandbox environment. According to Apple: Receipts for auto-renewable subscriptions can grow over time since the renewal transactions stay in the receipt forever. To optimize performance, the App Store may truncate sandbox receipts to remove old transactions. When validating receipts for transactions made in the sandbox environment, consider creating new test accounts instead of reusing old accounts to test subscription purchases.

Same here, no updates since July 20, 2021.

I am having the same problem since yesterday. I restarted the app but no luck. Were you able to fix the issue?
