Hey there,
Recently I am facing OAuthAccountNotLinked Error for new users when the new user complete their signup and tried to signin to my website InspireGem, they are facing this error.
Please open PR on this, if you know how to solve this error for new users.
P.S: Existing users is available to signin but new users are not able to do that. I tried a lots of solutions but none of them worked. Also working on these issue for about 2 weeks!
Please help me.
