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

I can report it is not an elegant solution, but it does work and you can name the station. 
 

Step 1:  

Open TuneIn Radio app.

Login

Choose library.  

Then Custom URL.

Enter URL and select it from list. (Must include full url)

TuneIn will open the station.

Press the heart button. 

Save as favorite using any name you choose. (You don’t need to name it the custom URL Address. 
 

Step 2:

Open Sonos app.

Go to Browse

Select TuneIn (New)

Must be connected to same account linked to TuneIn app  

Scroll to Favorites

Find your custom named station.

Long press on station  

Add to my Sonos
