It seems there is a update bug when you have more than one social connection of the same type in Auth0. I have created two linkedin social connections (linkedin (A) and linkedin-test (B)) in our Auth0 account via the Auth0 Management APIs.
This works fine and the two connections work correctly. However, when you try and update a connection via the Auth0 UI (Auth0 only shows the one of each social type), it incorrectly saves the settings to the other connection type.
IE Auth0 shows connection (A) but saves the settings to connection (B) via the UI.
