Runkeeper / playlists stop after three songs

[miguelito_de]

Hi everybody,

I use Spotify Running playlists together with Runkeeper. Everything worked ok, until three or four weks ago (except for "Detect tempo"). But since then, the playlists stop after the third song. (Spotify even looks like it was playing. Audio connection works - as RK information is still being played)
That's quite annoying.
Does anybody encounter the same Problem? Any solution suggestion?

Using:
iPhone 7 / Auto update for Spotify and Runkeeper, so the latest versions are installed.

Thanks for your help

Michael
