We installed 16 new Meraki access points with MR firmware 30.6. Currently, we have 84 APs operating on version 29.5, which were downgraded and locked to MR 29.5 due to issues with captive portals. Meraki support informed us that firmware 30.7 has been released and recommended upgrading to this version. However, I am reluctant to proceed with the upgrade and plan to downgrade all of them to 29.5, as we have experienced no issues with this version so far.
We will upgrade in the future but not now.
