Connection to RAUMFELD Speakers with IOS 10.2

[HST65]

Hi Guys,

I cannot connect my spotify to my Teufel/Raumfeld speakers, which are connected via WLAN with my ipad and iphone. Whenever a song starts it stops after seconds. Spotify works perfect with bluetooth and over the PC (but here not in the multiroom function).

Question: is there any bug with IOS 10.2 and Raumfeld/Teufel Speakers? Before my upgrade to IOS10.2 it worked perfect

thanks and best regards from Hagen
