Can't show my cameras on my Google Nest Hub

I was troubleshooting my cameras on my Google nest hub max and after reading all of the above I ran across this. I said hey Google sync my devices and BOOM they all became available after two years of working on this. It will pop a black screen with live but if you wait a few a live shot of your camera feed will come up. This worked for cam pan, V3 and doorbell pro. Hope this helps someone that has been banging their head off the wall like me for a long time.
