I'm unable to access Workspace and Level 1 Model Building 2.0 (New UX) though I'm part of Anaplan Certified Model Builder Program 15.
Pleas enable the same.
In any case support team can help or they will redirect you to the responsible team.
I Suggest to drop a mail to [email protected] that will solve your problem
@abhay.kanik : This is related to Certified Anaplan Model Builder program 15. I'm not sure if support team will be able to help
