Tune In /MP3 Radio stream, Title and Album not displayed

first, very great product. It works very good. But I have one thing. I’m using Tune In to play radio over a up2stream mini and pro.
This works fine, but sometimes it is showing in the app a Title and Artist in the app, sometimes not and sometimes just a very old artist same over the HTTP-API.
Especially it would be Interessting for the German Radio station 1Live.

has anybody a clue what I can do about this?
