Wyze bulbs not connected to the internet

Hello, first time posting so sorry if not in the correct place.
My issue.
Wyze bulb 2019.
All was fine and working via app. Internet was changed to google and they installed this egg looking mesh thing.
So from what i read it does NOT have seperate bands that you can choose. (5g vs 2.4) Apparently your device automatically connects to the most apropiate. I use iphone snd its seem to be connecting to 5G.
Ok…so i read snd read snd decided to buy a TP Link extender that ONlY works on 2.4.(to ensure only picks up 2.4 from original router)
I install and proceed to install the bulb again. All is looking good and i select the name Bedroom Light.
My phone is conected to the newly cinfigred 2.4 extender signal and even “deleted the other networks)
So bulb us installed and showing in the wyze app BUT no response at all. I turn off, on, dimm, and nothing. Not working. Any ideas?
Thanks
