I seem to have a similar issue as previously described. I have been trying to get the new SmartThings iOS app to work. When I log in I have no devices. When I log into the ide I seem to have 2 locations, both of which have been set to default. Unfortunately the new smartthings app does not show my original location with all of the devices added.
I have contacted customer support and have been waiting 3 months for an update, when I chase it the response I get is that they are working on it and nothing more.
Has anyone else had this issue / any ideas on how to resolve it?
I want to say choose the location with the hub and set it as the default and then delete the other location. But sounds like you have tried that. If support can not resolve, just rename the empty location, if you can, and forget about it. Not really what you want to hear.
