I was trying to tweak some setting of my K950 unit via Samsung Multiroom app. It suddenly lost connection to the Samsung multiroom app and I can't connect it thru anymore. Followed the instructions on the app, tried power cycle both the soundbar and phone but to no avail. I also tried to pair the soundbar with my phone with bluetooth and it wasn't working anymore. The soundbar works fine with the existing connection to the TV, PS4 and computer but no wireless connections to my phone. Please help.
