We are battling with these issues as well. The main concern is our clients being on Teams calls and observing a video freeze or an audio issue. This happens after few seconds of roaming to a different place on the same floor or sometimes even when the client is static at one spot on the floor but 802.11k,v pushing the client to roam. We are using 802.1x authentication with EAP-TLS. Currently running on Beta 30.1 on Meraki and with our Windows 10 clients and drivers running on 220.2. 802.11 K, V, R all enabled on Meraki side. The timeline on the health of dashboard shows up EAPOL timeout messages during all roaming situations. We rather dont expect any sort of EAPOL messages while roaming with 802.11R. The first feeling was our CoA is interacting with 802.11R and we disabled CoA.. However we continued seeing EAPOL timeouts. We believe the 802.11R is still not happening. Have been researching all the day along with our WPS tech-savvy and Our next step would be to enable PMK caching and pre-authentication on the windows clients (which apparently we found was missing) via Intune. Meraki TAC is continuing their investigation and I will tomorrow post them live captures during roaming & a time out.
