I have checked for updates, but they are on the latest version.  I have connected the switch to a different Deco and it still didn't work.  I will swap the main deco tomorrow and give it a shot.

I was going to ask if you confrimed the switch was still working but since you replaced it and replicated the issue that is likely not going to be a factor.   We would first suggest checking if there  are any updates avaialble to the deco or deco app and installing them.  Next Try connecting the switch to one of the remote decos.  If that works swap that deco out and make it the main deco and the current main deco to become a satalite unit.  Start there and let us know how it goes.
