I know its an extra dumb question, but it doesn’t hurt to be extra clear: so this means we deactivate this option:
and we follow the new instructions to create an entirely new link to LinkedIn, right?
I have no memory of how I created the OAuth ClientID on LinkedIn when I first configured this seven years ago, but the new documentation (which is excellent and easy to follow, btw, thank you! 
) led me to create a page for my “Organization” on LinkedIn, something I apparently didn’t need to do back then. Or maybe I didn’t have to do it now either and could have reused the old client-ID and secret?
Nevermind, why not have a LinkedIn-page for the forum, LOL.
My point is just to clarify that these are the steps existing users of the plugin need to follow:
- Deactivate the old plugin (eventually remove it from the yml file, but I guess that can wait)
- Follow the new instructions as if you never used Login with LinkedIn before.
- Done
