Note
Each version of the CM for SGNL app expires approximately every 90 days. You must upgrade to the latest version to avoid any disruptions and continue using the service.
If your phone has not connected to the Signal service for more than a year, you may need to re-activate the app.
If you have enabled a registration lock, the lock expires after seven days of inactivity, allowing you to create a new lock.
