I am logged in and not seeing my class anymore. 

STEP 1 - Make sure you are logged in with the correct account. Sometimes users end having two accounts and they are logged in with an account that has no access to the class. 

To check which account you are logged in with, click on Settings > Account Settings > Change Email Address and see which account you are logged in with. If you are logged in with the wrong account, please Sign out and Sign In with the correct account. 

STEP 2 -  As per STEP 1, if you are actually logged in with the correct account and still not seeing your class, please write to support@bloomz.com.
