I reset a Samsung button and removed it from the hub, then trying to re-adding it (also made sure it had a new battery). I went through all the steps without any problem, but then at the very last step when the app display “Succcess”, it stuck. The “Loading …” icon just kept spinning and never ended. I tried to add another button, and it did not have the same problem. Reset and re-added several times, but kept having the same problem with that button. Is the button dead?
I also have this problem. I tried to add with two different devices but it always stucks at success. Just keeps loading after that.
