I use libraries a lot for networked assets and libraries across my team, and the cloud keeps failing to inialise for InDesign or Illustrator, but will then work on every second day, or always on Photoshop. Restarting doesn't help, and in an enterprise system we can't edit, delete or reset user app data directly. I don't understand why the Cloud won't initialise for various programs on different days. It didn't used to do this until recent updates, but I can't say which because it works every few days.
