Any alembic experts able to provide feedback?  
I’ve exported my alembic files with animation several times but after importing in Unreal, dropping in Sequencer and adding a Geo Cache track, my animation is always missing!  
Attached are my import settings. I’ve also enabled both GeometryCache plugins.

Also can anyone point me to an animated .abc file saved in OGAWA format that is KNOWN to be working?  
I even tried the official Epic documentation but the sample .abc file does not seem to work.

Throws an error on import

> HDF5 Alembic files are not supported. Please convert the file to Ogawa format before importing.

I’m having the same issue, did you ever figure this out?

Update: if this helps you, I was able to get it working by importing my alembic from Maya into Blender first and then reexporting from there, still have no idea why it won’t work directly from Maya

Are you exporting Ogawa formatted alembics from Maya? HDF5 is a legacy format and is not supported.
