Help I have a beam gen 1 and 2 one sl as a basic home cinema system. The connection between the three keeps droppingI keep factory resetting the one sl"s, one shows then when I connect the other both diappear. I can tell you how many times I have rebooted. It has worked fine for months but recently (updates?), nothing works. I am so frustrated that I am close to chucking them in the bin! The Best I get is 2 showing in the app but not all three! When connect the third, that's when it goes wrong. Any suggestions as this is supposed to be plug n play. The router is WiFi 6, in the same room and no physical barriers, so don't pass the buck and blame the router. Help
