Why is "Restore Purchases" not working in LumaFusion?

In the Help and Settings menu under the Features tab, there is a button called Restore Purchases. This function is for restoring access to previously purchased features that might have been disconnected. Our current offering of paid features include:

• Creator Pass
• Speed Ramping & Enhanced Keyframing
• Multicam Studio (iOS version only)
• FCPXML Export (iOS version only)

If a "No purchases were restored..." message appears, then either the features are already accessible, or they have yet to be bought. These features are not included with the initial purchase of LumaFusion, so an additional purchase is required for use.
