Volume control missing from rooms in new app?

I have the same thing.  To be honest the new role out of this app has been super buggy. I'm surprised at the poor quality control sonos has had with this roll out. 

I'm my set up the main bedroom missing the volume controls is the playbar. 

Hi @nielsoost & @Dan_39 

Welcome to the Sonos Community!

Thanks for reporting this - sorry to hear of the issue you’re both having!

The next time you see the dot missing from the volume slider for your Playbars, could you each please submit a diagnostic and let me know when you have done so? Thanks.

There’s no need to post the given numbers here - please don’t, in fact.

Once I have diagnostics, I’ll pass them on to an engineer colleague for investigation.

Thanks again!

I’m having an issue with the Sonos app where I’m not able to control the volume for certain speakers. The volume slide control is just blank for some speakers.

Just after the problem occurred again I made a diagnostic:

please let me know how to fix :)

Have the same issue. 

Hi @nielsoost 

Thanks for the diagnostics - I’ve passed them along to a colleague. There won’t be anything you can do to fix this (or it seems unlikely, anyway). We will investigate.

Hi @Gilley 

I found some of your diagnostics too, and passed them along. Thanks!

Same problem with last Sonos product in the list. Agree with the other comments this version release seems to be full of bugs.

I am not that familiar with the Sonos community but I’m going to give this a shot.  The missing volume control  has been a regular issue for me too.  I am going to submit diagnostics after I send this message. 
I hope someone can help. Thank you.
