Unable to Share CC Libraries

My office uses Adobe CC and it would be incredibly helpful to utilize shared libraries for quickly sharing assets, as well and maintaining continuity across teams. I have been having a very frustrating and discouraging issues for months now: ADOBE LIBRARIES ARE UNSHAREABLE!!!

When I share links to my co-workers they either never receive the invitation, or the library never loads even when the invitation is accepted. My co-worker noticed the "syncing" symbol spinning in the library window in Illustrator but that was yesterday and still...nothing. When I inspect the status of library invitees, it says they are still "pending" even after accepting the invite. Not great for productivity on large teams. If anyone knows of a better program where this feature actually works I would like to ask my company to make the switch.
