Notifications showing "(Encrypted)" on iPhone/iPad

Push notifications that we relay through Apple's servers are encrypted with a per-device secret as detailed in this article. When the Pushover application's notification extension on your device receives the encrypted notification from iOS, it decrypts the message and then returns the unencrypted text back to iOS for displaying or forwarding to an Apple Watch.

On rare occasions, the notification extension may fail to start for some reason and iOS will show the unencrypted text of the original notification, which is just the string "(Encrypted)".  Unfortunately we do not yet have a root cause for the notification extension failing to start.  We have heard from users that this problem may coincide with recently updating the app from the App Store, so we recommend first restarting the device to see if the problem is resolved.  If not, we recommend proceeding with these troubleshooting steps.
