I'm so over these routers and looking at this forum is everyone having the same problem?! I've separated the channels, disabled everything. I'm at my wits end before I sell them on. Specifically IoT devices like doorbells, cameras, thermostats. I never had any problem with my Netgear Orbi. And I don't believe this is down to WiFi 6, already disabled that on the 2.4ghz network.
