IRIS Panels AES67 & Static IP settings are lost after upgrade?

The issue is fixed in EHX V12.1 software:

If the IRIS panels are running the panel firmware from version V2.30.75.0 or earlier, they will lose the IP settings during the upgrade.

If the IRIS panels are running the panel firmware from version V3.11.73 (Official EHX v12.1) or later, they will keep their IP settings the next time they upgrade.
