R850 Mesh Support in SmartZone

[GreensTheorem]

Does the R850 Support Mesh in SmartZone as Root AP or Mesh AP?

I had two separate occasions, one with vSZ v6 and one with SZ124 controllers on v6.2, where I tried to deploy a mesh with R850 APs but failed.

All R850 APs were provisioned via cable connection and all automatically took the RAP / root AP role. Then one R850 was disconnected after provisioning and powered via PoE injector, while still being very close to another AP that showed as root AP.

However, the AP that is now connected via injector did not connect via Mesh to the other APs.

Mesh was of course enabled (both mesh and Zero Touch Mesh)

Any ideas? Is this R850 specific?
