@rjskene83 we changed the way we retrieve the profile from Yahoo a week ago because Yahoo is deprecating the endpoint we were using.
We notified customers that had active usage of Yahoo connections. The documentation is here https://auth0.com/docs/migrations/guides/yahoo-userinfo-updates
Make sure you select in Auth0 the same Permissions you select in the Yahoo application.
If that does not fix it, please share with me your tenant information by private message so we can check if there’s something special going on.
Regards,
Andres
