Recently, we received an user enquiry regarding the inability to perform bookings for the app. After investigation, we found that the issue appears to be caused by the failure of the Apple DeviceCheck service.
Based on our checks, approximately 0.01% of requests fail each day (e.g., on 26 June: 6 failures out of 44,544 requests) when using Apple DeviceCheck.
Could you please assist in raising the following enquiries with Apple Support?
- What is the typical failure rate of Apple DeviceCheck? Are there any reliability metrics or benchmarks for its performance?
- How can the failures be prevented, or is there a recommended retry mechanism to handle such failures?
- Does the iOS version affect the performance or reliability of Apple DeviceCheck? Are there known issues or limitations with specific iOS versions?
- How long does the token remain valid, and when should a new one be retrieved?
- Does using a jailbroken device affect the functionality of Apple DeviceCheck?
