Cannot Verify LumaFusion Purchase Message (iOS)

As of February 2023, some LumaFusion customers may have seen an “Unable to Verify Purchase” message when they export their movie (Tap on the Share/Export button). This was due to an outage of Apple’s receipt verification system, which has since been resolved.

To remove this message, make sure that you're updated to the latest versions of LumaFusion and your operating system, as well as to sign out of the App Store then back in.
