After working fine for over six months, few electrons under my account had stopped responding. On running diagnostics, device vitals, SIM card & Device Cloud are showing healthy but the Cellular Network is showing the following warning - Outdated Session Data.
The cellular session was reported as inactive, but your device was responsive to the Device Cloud. This discrepancy is likely due to latency in session data reported by cellular carriers, which causes these tests to temporarily become out-of-sync. This issue normally resolves itself within a few minutes.
The user firmware has been stable over six months, so we don’t suspect it has something to do with the user firmware. The device is running DeviceOS : 0.7.0.
What can go wrong for this to happen?
