I went to access my library in photoshop CC 2018 and I get the message.
To use creative cloud libraries, please sign in to Creative Cloud.
I went to check to see if I was signed in, and I am signed in.
I know I am signed in, because my profile image appeared on the welcome screen before I loaded in a psd file.
Can someone please advise me how I can be signed into Creative Cloud, and yet be signed out for the libraries.
The issue has been resolved, as I sign out of creative cloud and signed back in.
Not sure why I had to sign out and sign back in to resolve the issue.
