Hey benrounds

Thanks for reaching out. My apologies for the late response.

@RachelGomez123, I appreciate your help here! I know how challenging it is when you can't create a speaker group on the Google Home app. Let's dig deeper into this. A few questions: when did the issue start? Have you tried using a different phone/tablet? What is the Google Home app version on your phone?

Let's go ahead and try to factory reset two of your devices first. Once done, check if you can create a group with the two speakers. Please note that resetting your device will remove all the settings on your device and go back to the default settings.

Let me know how it goes.

Cheers,
Muddi

Hi Rachel, I'm using the Google Home app on my iPhone 12 Pro and all devices are connected to the same WiFi. 

I'm able to make media play on all speakers at once by selecting the three devices in the app. However, I'd like to make this more efficient by creating the speaker group, and this is where I'm getting an error. 

Do I need to potentially reset all of the speakers?
