I have a question about APNs specifications. We are aware that if we delete the app, we will disable the device token managed by APNs. we intend to send a push notification from AWS SNS to APNs and if the device token is disabled, AWS SNS will identify that the app has been deleted from our phone. I believe the specification is that iOS uninstall data is only available after the 8th day. However, it has been a month since the uninstallation and still the APNs are not returning the device token as invalid. Why is the uninstall data not available? If there is a way to do this waiting up, please let me know.
