Hello,
So I downloaded the Unity Playfab Editor extension and imported to Unity (I'm working on Unity 2017.3f Pro), tried to login with a previously created account from the website and I it would throw me an "invalid email/password" error. So I decided to créate a new account from the editor extension with a different email address and it did work, it would log in with the new account and everything seems to be working. But I didn't receive any email on this new email address and I can't log in with this new account created from the editor extension in the website.
So what's going on is I have 2 accounts, one that I can log in from the website but not from the unity editor, and the other one that I can log in from the unity editor but not from the website.
Any help is greatly appreciated, cheers!
