you are wrong. It DOES NOT work with the current version of AE.
I read the compatibility before buying. Despite what it says it does NOT work with the current AE. All it did was waste my time against a deadline. I want my money back, take the license. I highly recommend you update compatibility listing to indicate that it is NOT compatible with the current version.
In version CC2017 and higher, the composition markers became available for the script, so an additional layer became unnecessary.The composition markers are directly synchronized with the composition layer markers in another composition.
