Thank you to everyone for being so active in the Meraki Community. We have identified the issue which has been causing MS22, MS42, MS220 and MS320 switches to require a physical reboot during an upgrade. The issue is present on switches currently running MS 9.0 and above. We hope to rectify this issue and provide a fix shortly. In the interim, we have discovered a reboot of the switch via dashboard prior to performing an upgrade will prevent the switch from becoming unreachable. As always, if you have any further questions/concern, please do not hesitate to reach out to our Cisco Meraki Support Team.
