Here's my take on this...
In case a configuration change causes connection loss to the cloud the switch would do the following:
MS
- If the configuration is safe
- If the configuration is not safe
- MS will try to obtain an IP address on an alternate VLAN and then connect to the cloud through that alternate connection
- MS will revert to previous safe configuration 2 hours after lost connectivity
- After reverting to a safe configuration, the former configuration will be marked bad
So worst case if it can't connect to the cloud over another VLAN it knows about it would revert to the correct config after two hours. That said, in the local status page you can change the native VLAN. If you change it to a VLAN that can get out to the internet I suppose the issue would also be resolved.
