Hi Adam,
Monitoring the device running version 12.1.4 of the supervisor and performing some tests I wasn’t able to replicate the ‘Network changes detected’ or observe the behavior. Although we are stilll investigating to find the exact cause, we are fairly confident that this new version fixes the issue.
We are working on getting some details ready on a new release that we expect to put into production soon for the dart imx8mm device type.
In the meantime let us know of any new issues you observe on your devices.
Cheers
