That is correct, actually MR72 is no longer advertised in Meraki page, we have been wondering the same question, specially after Meraki support told us that this was a known issue and that the engineering team was trying to figure out how to correct it, we have updated firmware version as suggested and still going offline. We wanted to share our current experience so anyone considering upgrading now think about it twice, or wait until a fix comes out. And see if anybody has been able to fix it...

Hi, We have the same situation here, but we have a mix of MR32's, MR72's and MR74's, the only model presenting that offline issue is the MR74 model, same as other posts, they become unreachable from the portal or clients, only workaround now is turning the switch port off and on so they can work again. We currently have 17 units with the issue, Meraki RMA us 3 units to test, but as soon as we connected them, they went offline after 1 day of operation together with the rest of them. We now have tickets open with Cisco (We use Catalyst 6800's switches) we just finished a support call this morning, they went through our configuration and everything is ok according to them, also Meraki support ticket for reviewing the Meraki configuration, which they also say is correct, so at this point we are bouncing back and forth while our production is getting affected and IT yelled at for not fixing the issue 😞
