Working with vector Illustrator files in After Effects is still very clunky. Yes, you can import .ai files into AE, and even convert them to Shape Layers in your comp. But what if you make changes to your Illustrator file? Or what if you add something in AE that you want to update in AI? Or want editable text? You're out of luck. The script called Overlord by battleaxe.co solves these issues and more. Their solutions are excellent, but we shouldn't need to buy an additional script just for simple workflow stuff that should be built into your software. You'd think AE and Illustrator were made by two completely separate companies based on how poorly they talk to each other.
Adobe, please make some progress here! Things have really stagnated the last several years when it comes to simple workflow stuff like this between your programs.
