Essential graphics currently is buggy.
There are several problems that my team have faced due to essential graphics.
illegal xml character
When a text has a line break done by "Shift + enter", instead of "enter".
This creates a illegal xml character that can only be seen by pc and not mac. Space in the text becomes this small box which causes multiple error pop ups during file opening.
Essential graphics still exists in a reduce file.
Although the project has been reduced with the composition with the essential graphics deleted, saving this file after and dragging it to any project or opening it will cause an xml character error. Using scripting, previous Essential graphics properties can still be found.
Property names changed back to default property name although it's renamed in the essential graphics window. This happens only to AE2020 and not AE2019
