Why is the mobile app showing “Server Not Available” or “Town Server Not Connected”?

First step: verify the sync is running correctly. If it is, check the mobile device’s network connection.

This issue is specific to SDL Mobile 3 and how its older sync client communicates with the backend. Since the newer sync process doesn’t fully align with how SDL Mobile 3 expects data, the app can sometimes report the sync as “not running” even when it’s fine on the backend — this is often simply a mismatch between the device’s OS version and SDL Mobile 3’s current, fairly fragile state.

Recommendation: move affected inspectors to SDL Field, which has more reliable sync behavior overall.
