Problem
Push notifications are failing due to the "Requestedentitywasnotfound" error.
Explanation
This error occurs when the FCM token you are trying to use to send a push is no longer registered. It is treated the same as a "NotRegistered" error, meaning the app may have been uninstalled.
Solution
Perform the following steps:
- Reconnect to the database.
- Ensure all tokens are active and in use.
- Delete or update any unused tokens.
