I like that it is easy to use for both internal communications as well external ones! It has helped us keep everyone connected throughout our organization without having too many different platforms or apps open at once (which can make things confusing).
We have had some issues when using other people's accounts while they are logged out but overall everything works great so far!! The only thing i dislike about Communcations platform would probably just come down t o its ease-of -use factor because there isn't much else wrong here if used correctly! If anything what helps most wth communicating internally through messages/emails etc instead going back n forth via slack which sometimes gets annoying :D.
