SwitchBot unavailable on firmware 6.2

I have two SwitchBots, one was on firmware 4.7 and the other 6.2 so I could do the multi-press for on/off. After the HA upgrade to 2021.11 the one on 6.2 was always going unavailable. Didn’t know if it was interference or firmware. I upgraded the 4.7 switchbot today and now both are going unavailable.

Anyone else experienced this?
