I have purchased a Custom Drag Model but it is not showing up.

Google play does not always instantly apply purchases. If you have previously purchased a CDM, and it is not showing up try these two things:

  1. Make sure you have given google time to process the purchase.
  2. Try the Restore Purchases Button located in the app. You can find out more about the Restore Purchases Feature in the User Guide:  AB Mobile User Guide
