Anchor Alert App Pro - my app has frozen / crashed when I start an alert session

Why the Anchor Alert App needs a minute to start an alert session

When you start an Anchor Alert App Pro alert session, you may notice the app screen shows a spinning wheel for up to a minute before the alert session starts.

This is expected, and your app has not frozen or crashed; it's waiting for the DataHub to start the alert session and configure your alerts before it continues.

The DataHub is an ultra-low-power device which does not have a fast CPU. The CPU has ample speed to run all the apps which are active on it; however, it is not quick to start an Anchor Alert session because starting an alert session requires starting the app on the DataHub itself, enabling each of the active alerts, and initializing the PredictChat app which sends alerts to your device over DataHub Wi-Fi and cellular via Apple.

If your app has not unfrozen after one full minute, please try a factory reset of the DataHub. This may be required to allow the updated Firmware to work correctly. Please take note of your DataHub's existing settings for NMEA, Internet, PredictMail, etc, then go to DataHub > Services > Settings > Maintenance and click on PERFORM RESET. Wait 3 minutes, then reconnect to DataHub Wi-Fi and try again.


A factory reset will not delete any files on the DataHub SD card, so your existing PredictMail messages and logs will not be affected.

If this does not work, please contact us at Support and if possible, do a screen recording of what you see or make a video from another phone and share it with us so we can help troubleshoot it.
