Disappointed again!

Why is it not reliable!!!!
Im using the multiple room function on the latest iOS on my phone. Yesterday the deezer kept skipping after 30 seconds of playing song. The tuneInn app kept stopping. Today seems fine... So unreliable!

I cant download the Samsung link onto my Mac laptop (not supported) to stream my music onto the speakers. The sound is good for my expectations. The programming of the app is really bad! You people need to improve this asap
