@TimHockley did you manage to solve this issue somehow? I’m also experiencing similar problems; when dropping connectivity due to poor signal, and the Electron stays in that area for a longer period of time, going back into areas where signal is good the Electron just keeps flashing green without being able to reconnect to the cloud. I’m also unable to call Cellular.off to try and reboot the GSM-module. The only solutions I found so far is manually resetting the device, which really is sub-optimal for my application.
