There is possibly same reason than with anything else like "Samsung Community Terms and Conditions": "Couldn't load webpage ... Error 400: Bad request"
Login to the phone App didn't work after 6 months when I bought the activity bracelet. Had to reset all to zero and didn't even work after that. Lucky me the store helped me little and offered me almost free next level device. I suppose there is same thing with this now that had with the other 6 months ago.
Samsung devices just don't work properly even with the apps and phones where those are planned to work with. Like Samsung Pages does not appear there where they should be etc.
Blame the greedy company, bad or even worse programming or seriously worse planning of the apps and devices functionalities like only backup plan is cloud (to give greedy company my personal info to analyze).
