No more TuneIn URL streams anymore, guess I am returning my two Eras :(

To elaborate on my previous post:

1.  As ​​​@controlav commented, this facility has never had anything to do with TuneIn.  It was just a convenient slot to put the info in.  It is and has always been a direct URL that Sonos uses to get the stream tthat is made available by the station.
2. I added a URL a few minutes ago by following the instructions in the document linked by @Runjoey (which is how I have always done it)  I used the desktop app but the facility also still seems to be in the mobile app.
3. The created station still appears in “My Radio Stations” under TuneIn.  It still has absolutely B****r-all to do with TuneIn,
4. The station can from there be added to Favourites.  It was always thus and still is.

What are the grounds for believing this is no longer possible, or that this is going to change?  The answer cannot be that “TuneIn has dropped support” for this, as @Runjoey suggested, because TuneIn has never supported it.

Well, it’s not what you’re missing, I t’s what I’m missing. When I select TuneIn, I no longer have an option for “My Radio Stations”.

Shouldn’t there be a TuneIn old (which is indeed going away) and a TuneIn new, that does not allow added streams?

You are correct, but nonetheless, as you say, the old is going away (and with it, the only method we know of, to add a direct URL.

No luck, but thank you — I appreciate the suggestion. That was a good idea…. giggling the cable, so to speak. 

Personally, I feel this is a money issue. And companies have to make money—I get it. But we’re transitioning into an era where, when you buy a product, you’re limited in what you can do with it. Your freedoms are within the constraints of the ongoing “service”.

Everyone wants a piece of the pie. I’m guessing that with streaming a direct URL, someone is losing a nickel and they don’t like it. Solution: get rid of the URL option or, at least make it difficult. In the end, the consumer loses. 

I just happen to have three URLs I like to stream. I donate money to these independent stations because they find and play music I can’t hear anywhere else. It’s that simple.

This is my uneducated (or “blind,” as stated above) opinion and it certainly may be wrong.

You can no longer add TuneIn (Classic) to any system, and if it isn’t there, you can’t play your custom urls. If its already there, well you’re fine, until such time as Sonos force-remove it or TuneIn disable the old endpoint.

You are correct. I think this is what others may not understand as they may still be on TuneIn’s old interface within the Sonos iOS app. For those with TuneIn’s new (and improved???) interface, the option to add a direct URL appears to have been removed. (And if anyone has found this Easter egg in the *new* interface, do tell.)

You can use my iOS app to add custom URLs to your Sonos system, if you don’t have TuneIn (Classic) on your system. Or use the Desktop Sonos app which has it on the main menu instead of in the TuneIn UX tree.
