Device Locked in Single App Mode and Lost Connectivity
We currently have iPads that go out to various locations throughout the states and are pre-configured via Apple Configurator and with profiles for a network specific to that location and a separate network utilized for hotspot troubleshooting. Once at a location, we have to lock down the device in Single App Mode. Though, when the location changes their WiFi password without informing me first, and the device loses communication with Meraki - the device is stuck on a "white screen" until I can get it back on one of the WiFi profiles built it.
Is there a workaround available that I am missing so that we can unlock the devices or allow for network changes without communication to Meraki?
HOWEVER: iPads do support ethernet so there's a possibility you could plug in a USB-C to Ethernet adapter to get them back online without a reset
For the future, I always suggest that you provision the devices with TWO SSIDs, one of them being a guest SSID. The iPads will naturally default to the most secure security on an SSID, but, if that's not available, should then join the Guest WiFi, allowing for continued connectivity.
