Hi @UnsureAboutU
Welcome to the Sonos Community!
Sorry to hear about the multiple issues you are having with your Sonos system.
Regarding Google Assistant, there are a couple of other threads:
We have so far been unable to recreate the issue in our own testing, so we are asking for help from affected users on that thread - please only pay attention to the posts from me from yesterday onwards - we have moved on from troubleshooting steps.
Recently, speaker groupings not working have often been down to a speaker or two’s software not being quite as up-to-date as the rest of the speakers on the system. Please perform a manual check for updates: Settings icon » Manage » System Updates » Check for Updates.
I do understand your frustration, but if you are willing to give our technical support team a call, they may be able to resolve the issues you are having - asking the speakers about what is going wrong is invaluable.
I hope this helps.
