Months ago I did it. But the problem started when I received a message that Webcore needed to be updated of some sort. I must have did the update wrong and then nothing worked afterwards. But I had it working using my Samsung account and new app for months.
Now starting over, im trying to use webcore using a different recently setup samsung account (brand new hub as well). I first install and load webcore to my samsung IDE, then initiate it using the old smartthings app so it shows in the new Samsung app. But regardless from where I try to register a browser from, I received the error above.
Thanks for any help you could offer.
