I just checked the Cisco Visio link (https://www.cisco.com/c/en/us/products/visio-stencil-listing.html) and the Meraki stencils are no longer there...are they being brought up to date?
Any idea when they will be available again?
You can find the Visio stencils here:
Search the page for "Meraki". Although they are under the security heading, the stencil includes MR Access Points, MS Switches, and MX Security Appliances.
