were you logged in when you were doing the challenges yesterday?
are you sure you have logged to the same account? the freecodecamp account is linked to your email address, so maybe you have logged in with a different email address? maybe with the wrong google account?
Oh I thought I logged in with my gmail but it turns out my account was linked to facebook profile. It’s OK now.
I feel stupid for opening new topic for this
it seems the facebook profile has a different email than your google account. If you want you can change the email associated to your account in the settings
