I'm having issues connecting Nest Mesh to my 11 smart devices that require 2.4 GHz to set up. Google Support has been worse than non existent. The support page for this issue is blank, and after a week of hassles, and being on hold for hours they were a no show for an 8 AM phone consult this morning and closed my case. Their chat isn't open and they aren't answering the phone. DON'T BUY THE NEST MESH!!!!
Sorry for the late response here, and for the frustrating experiences you've had with support, but I wanted to check in to see if you were still having this issue and to see if you have done any troubleshooting so far. If you still need help, let me know and I'll be happy to work on this with you.
