#pherephone boost to pleroma Y U NO WORK??

This is a #pherephone “Announce” activity from a writefreely post. It works on mastodon but not on pleroma. I cannot understand why this is. Can any helpful #pleroma or #ActivityPub experts give a hint?

boosts appreciated

EDIT: I also tried after reversing the cc and to fields just as pleroma does.
