Hi there,
I have been experiencing this issue for a couple of weeks, since I got a new iPad Pro. I have a subscription to Adobe CC for all programs. I am logged into my Creative Cloud across my 3 devices; I have a MacBook Air, iPhone 6 and iPad Pro. On my MacBook Air, all of my libraries appear in the libraries panel in all of my adobe programs, mainly Illustrator, Photoshop and InDesign which are what I use from day to day. On my iPhone and iPad, depending on which app I open, I don't have access to any or very few of my libraries. What could be the cause of this? I see that some apps do not support the libraries, but for example, in Adobe Comp, I only have access to one library, but it shows no assets inside. When I access this library on Adobe.com, or through my Creative Cloud panel on my desktop, I see all assets there. It seems like there is a syncing issue somewhere, but I can't figure out where or how to properly sync everything. I have tried logging out on all devices, logging back in, shutting down, restarting, and checking/installing any updates. Am I missing something? Any suggestions are greatly appreciated!
