Sub control not working after the updating the Sonos app

Latest app update on my device, just tested and for sub eq settings none of the adjustments make any impact on the sub. That is sub on/off, sub level and sub crossover. Nothing changes at all when these are adjusted in the app. So annoying

Actually just tested EQ and those settings also do nothing on my system. Just the worst.

I see they have time to moderate posts on this forum, but not time to acknowledge there’s a problem or to provide solutions. 🤦‍♂️
 

I’ve comes from loving Sonos to loathing it. Forced updates is not something that should ever be needed. And worse if they break the product and then there’s no fix. 
 

My concern is that a buggy OTA update has bricked their sub. Why else would their be no fix, and no response after all this time?
 

If anyone’s recently purchased their Sonos gear, it might be worth getting a refund for not fit for purpose.

If they ever do get this fixed, I’ll be looking to configure a firewall in my home router to block any network communication to Sonos in future. 

This is, for better or worse, a Sonos community forum, not a forum to communicate with Sonos support. Occasionally, the few Sonos moderators jump in when they can, but it isn’t frequent, and given the explosion in posts over the last several weeks, I suspect they are so busy tracking and moderating that they have a hard time responding to every single post, and every single thread. 

If you want to, you could call Sonos Support directly to discuss the issue you’re experiencing with your system.
