I have the 4 drivers and the app installed...OATH etc as well.
When I try to add the Spruce Connect app I got to the page asking if I want to allow the connection...and I answer yes. It goes to a cyan screen with black text that says to close that session and relaunch the app.
Then I close my browser and readd the app ...and I get exactly the same thing. Over-and-Over.
I have deleted all devices and apps and reinstalled multiple times and nothing changes.
