We have 19 MV cameras, after upgrading the firmware to this version, we some cameras stopped working.  This happened, 20 March 2023.  After the upgrade, around 9 cameras stopped working.  After a few weeks, 4 cameras came back fine.  As of today, 5 MV72x cameras are still not working.   Current situation: - 4x Faulty cameras still have network connectivity.  We can still ping it and power is up. - 1x Faulty camera was taken off and was reset.  It was placed back to where it was mounted before but no connectivity anymore. - 5x Faulty cameras are no longer working for 4 weeks and causing a lot of security issues on our physical assets.   What we did so far together with the supplier: 1.  Power off the MV72x via PoE on Meraki switches 2.  Restart the Meraki switches around 3 times already 3.  Open Access policy on the Meraki switches from sticky mac 4.  Waited for more than 4 weeks as Meraki promised that it's going to come back up eventually.   There is now a pressing concern about physical security within the area and Meraki cannot give an ETA.  We are now looking at finding a replacement using the Verdaka solution as Meraki support is hopeless and doesn't like to stand by their product.  Meraki doesn't even want to replace 5 cameras that are not working due to firmware updates even if all are still under warranty.  HOPELESS!!!!!!!!!   ...
