Plugin does not seem to be handling users with multiple log in methods correctly

We are using the 3.11.3 version of the auth0 wordpress plugin and according to the docs at step 8 it should allow a user to log in even if their auth0 user ID in user_meta doesnt match the one in auth0 to suceed as long as their email is the same (it will apparently search for a matching user email).

For us however this is not working, this means that we are unable to have users currently with more than one log in method and also are not able to convieniently set our dev server to use our dev tenant as it is treating our dev user logins as invalid showing a ‘a user with that email already exists’ error (or whatever the wording is).

Any thoughts on why this may be happening? Does this work as stated in the docs for other people?
