I am kicking myself y'all! If I could go back in time!!! I majorly invested in these Google devices.... I have about 15 nest mini speakers, 3 Nest Audio, 5 nest displays and two wired doorbells... all of which are absolute *hit. Streaming music is such an effing pain! I have wifi6... it's garbled. It's choppy. I have rebooted the speakers. When I stream Spotify to my home Speaker group, it's total misery. If I only stream to one device it's great. I can't even get my doorbell to sync to my nest displays so I can see who's at the door. I also got two chromecasts even though I have smart tvs to see if it would show me who's at the door on my tv...ummm HELL NO. It is complete crap. Anyone who is remotely thinking of investing... please!!! Do not. I mean... I have some roku speakers... wowwww... easy hookup, awesome awesome awesome sound no problems what so ever. I'm sick thinking of the money I've invested in Google devices. STAY AWAY! I am in IT tech... it isn't me, my wifi, or the wind...lol! So upset! Stay far... FAR away!
It's frustrating when things don't work as expect for sure. I have a multitude of Google devices as well, and besides some spotty speeds with the Google wifi occasionally, everything works quite well. Every home is different when it comes to signal dead zones and interference of course, so that could be possible in your case. If you have any questions I'm happy to try and lend a hand!
