I'm trying to develop a smart home skill. As you have to implement account linking for SHS(smart home skill) I used LWA(login with amazon) as oAuth provider. And now problems begin: login view is shown and I click allow but then I see this generic error: https://imgur.com/1JKvapP ("we were unable to link at this time"). I spent more that a week trying to figure out what's the problem. Went over all answers on stackoverflow, amazon forums, etc and got nothing. Checked my configurations 10 times. Zero results.
I just don't know where to look for a clue.
Anyone able to help me?
