It seems there was, in the BETA versions, a distinct menu item in After Effects for importing the PNG+WAV output from Ch. If not (sometimes I may not remember correctly for sure ...), do we import as just a "File" as a "PNG Sequence"?
I'm assuming this question is already answered as part of this thread: No Sign of Character Animator CC2018 in After Effects CC 2018
For others, you can look at this FAQ: FAQ: Importing exported PNG Sequences and WAV files from Character Animator into After Effects
