The endpoint is now functioning correctly for both the sandbox and production environments.

We have disabled our temporary patch that enables 1-day promotional entitlements. In addition, we will be replaying any failed receipt requests that we have received during the outage.

We're still seeing instability on the App Store's verifyReceipt endpoint. The sandbox endpoint appears to be completely unreachable, the production endpoint is failing about 66% of the time.

We've deployed a patch that will temporarily grant users that attempt to purchase 1-day of entitlement access until we're able to re-validate receipts. As long as your app is using the RevenueCat Entitlements system new purchasers will be receiving the correct level of access.
