I am waiting for italki Support to contact me back but maybe someone out there has figured this out.
I signed up for italki last year with an old email that I no longer have access to. So I don't know the password for this account. However, italki lets me log in with Facebook which has my new email. So I thought all was well.
Until this morning when I was confirming a session but it wouldn't take the Facebook password I use to log in.
