I am writing to express my extreme frustration and disappointment with the latest update of your app. This situation has brought me to the brink of packing up all my Sonos speakers and putting them in storage. Since the update, my experience has been nothing short of a disaster:

1. Speaker Detection Issues: The app intermittently fails to detect my speakers. They appear and disappear at random, making it impossible to manage them effectively.
2. Grouping Problems: When I try to split the music in one room from the group, the remaining speakers stop working and cannot be re-grouped. This has rendered the multi-room functionality unusable.
3. Playback Failures: None of the speakers will play music after attempting to manage them through the app.
4. App Connectivity: The app frequently loses connection with the speakers and is unable to detect them again.
5. Google Assistant Issues: The Google Assistant voice feature has been unable to connect and function properly for months. The support wait times have been consistently long and unreasonable, making it nearly impossible to get the technical assistance needed.

Moreover, the support wait times are exceedingly long, often over 70 minutes, and the chat support has not been helpful in resolving these issues. This situation is unacceptable and has caused significant inconvenience.

I urge you to provide an option to revert to the previous version of the app until these critical bugs are resolved. Additionally, I would appreciate a more responsive and effective support system to address these urgent issues.
