I have some content libraries shared between data centers. This worked a few days ago for me, as user "wsanders". Now, when I try to sync a recently uploaded library item as "wsanders" I get an error:
"The "Sync Library Item" operation failed for the entity with the following error message.
This method requires authentication."
To get the sync to start I have to log in as administrator.
The subscription URL on the destination library matches the one on the origin and I can pull the json down in web browser.
How do I start debugging this? Is there a separate role I need to set to allow all users to post content in libraries and share it?
