Spotify Radio not starting on iPhone

[LeTibo]

I have a daily issue when using Spotify artist radio on my iPhone (latest iOS version). Typical use case is as follows:

- Spotify app is closed but inactive for a few hours (i.e. I see it if I double click on the home button)

- When I reopen the app, and click on a radio to play it, the radio doesn't start and just displays a loading icon! Same for the 2nd radio I try, and usually by the 3rd radio I try to start, the radio successfully plays. But the first radios I start to play will never start.

- Sometimes, none of the radios start and I get the error message 'Sorry. This radio station cannot be started. Please try with something else" (I have a screenshot if needed)

- Sometimes the play button next to the radio just shows a loading icon.

- When I kill the app and restart it, most of the time it resolves the issue.

- I use Spotify on 3G, and use Spotify mostly for listening to the radio.

Thanks!
