You are connecting via Bluetooth they are trying to connect via ANT+. I was about to go buy a new S7 Tablet as well when I started doing some research and came across this thread. I have an ANT+ HR strap so If I buy the tablet I would have to buy a new Bluetooth HR strap. Both my Wahoo Kickr and my Quarq work on ANT+ and Bluetooth so that is not an issue. I just received and email from TR about not being able to do the new AT on Android 5 or 6 my old Tab S runs on 6 so I was going to go upgrade to the new Tab S7. I think for now I will just use my phone or just finish off my regular training plan on my old tablet and consider my options.
