I am having some recent issues with Disconnects and unvailable status 

i have over 40 devices in my home 

i also have 6 Deco M5 AP's so my wireless coverage is fantastic with a 1gb connection 

Lately the devices have started blinking green wifi signal on the swtich and shown up unavailable or non-responsive to Alexa.

Firmware is updated 

Weird part is the switch is in a two or three gang box wiht 1 or 2 other swiches and the others are not flashing or showing up disconnected

Couple of questions  

1. i recently added some new stuff at a second home controlled with the same app - coudl that be an issue?

2.  also am i getting close to some device max for my devices and connecting that i shoudl consider.- the issue seems to have gotten worse since we turned on some Christmas lighting controls 

Thanks in advance for your help
