Simply adding my feedback to this thread and confirming what have been said earlier as I'm facing similar issue since October.   We have several devices that don't support WIFI6 at a point they dont even see our SSID being broadcasted but only neighbors SSID which is really odd to me (known issue on several intel chipset apparently)   Meraki support did deactivate 802.11ax on both 2.4G & 5G Radios.
