When you want to add some elements from Mango Animation Maker, you may find that some elements are marked as PRO or ENT. Here, they will explain the implication for you.
Marked as PRO: It means that you can add this object to your canvas if your account version is upgraded to Professional.
Marked as ENT: It means that you can add this object to your canvas if your account version is upgraded to Enterprise.
If your account is already updated to the Enterprise version, you can use all the elements as you like.
