Hi, we recently upgraded to Meraki MX 450s and MS390/120 switches and ran into issues with the 16.16 firmware. The HA pair experienced Intermittent loss to Meraki dashboard cloud connectivity across both Internet circuits. Each circuit was tested individually while running 16.16 code and still experience the same loss. Equipment was rebooted with no effect. We also had routing issues between Azure Meraki vMX and on-prem MX. I originally had a route, for example 10.10.0.0/16 (which reside in our on-prem network) in Azure but it was causing all sorts of issues because it included some problem VLANs on-prem, so we had to split it out into 10.10.x.0/24 subnets for it to work. A downgrade was then performed to 15.44.1 software code which resolved the issues. We did open a case with support but no luck yet, has anyone seen this or have any ideas? Thanks.
