We are a school that just this past summer converted to all Meraki equipment.  We have a high density environment with 196 MR57s scattered across 11 buildings and are seeing all the same things everyone has been seeing ( massive unexpected disassociations, constant roaming of devices that are standing still, repeated disconnects and inability to reconnect making it impossible to have zoom calls, constant eapol timeouts, repeated connections to an AP "for a few seconds").     We have upgraded to 30.5 and it seems to have made dent into the connection problems we've been having.  It's not perfect by any means.  We still get some disconnections and looking at our connection log, there are constant authentication failures due to eapol timeouts.  Has anyone else tried 30.5? ...
