You maybe aware already, but just in case, you can switch-off contact via the App and just leave it via email if you prefer. The options are available in your Sonos online account profile.

Do you have "allow pop-up messages " disabled in the app preferences?  If not, that might help.....

Ok, I turned off the Sonos App Contacts Option and found the setting for no more Pop-Ups… which I will have to do on all my devices. Thank you for the helpful hints… lets see how they work…

As advertised, most likely.

So even with with Allow Pop-up Messages off I am still getting these.

Those settings do nothing. “Allow pop-up messages” is off. The “contact in-app” setting on my profile is off. I still get the ads.

These ads are a terrible, terrible, thing to do to users.

If you think this is ‘terrible, terrible’, I hope nothing serious ever happens to you.

Not trying to defend it, though.  It shouldn’t happen if you don’t want it to.  I never get them but I have no explanation of why you do.

In the context of a home speaker system, yes, it’s terrible.

If you want to say it’s not terrible, compared to, say, cancer? Well… duh. But this is a set of speakers we’re talking about here, right?

I think “annoying” would be a proper term, in the context of a home speaker system.  Terrible would be something that makes the product completely unusable, like lip sync issues, drop outs, no access to streaming services, etc.  I mean, if ads, are double terrible, where do you go from there?

To be clear, I do think you should be able to completely turn off ads.  If you don’t want to hear about the latest Sonos radio stations, you should be able to.

It might be possible to think of something worse that could be done to a speaker system, without a need to compare it with a serious medical condition.

OMG. Are you just here to argue?
