The option should still be there for playlist radio. Make sure you are on the playlist screen for the playlist you want to make a radio for, then tap ... and "go to radio" should be the bottom option. Alternatively, if you have "autoplay" toggled on in settings, after listening through the whole playlist, the playlist radio will begin playing automatically. Unfortunately, I don't see an option to save a playlist radio station to your playlists.
--> you can find your radio stations in the Search tab under Radio category.
( Mine ) no. The radio stations are missing. If I go to search, and browse to Radio category, I'll only see a list of recommended radios
2) previously I can generate a radio station from my playlist, which kept listening entertaining and fresh, and if I like that I can save it and referring to that later. Right now this is also missing.
I hate to say this, but, user experience and interface is so important and if there are increasing complaints and rejection vibe increasing, maybe Spotify UX team needs to be open to revert back to the older design . Thanks.
