Our team has successfully created and been using CC Libraries for several years. We have begun experiencing problems for the first time - after the CC app update Friday, Sept. 25, 2020. The following error message is displayed:
This fiile is already open by another user or another application. This file may be stoed on a network server and cannot be opened until the other user closes it.
We can see our libraries and even see the objects in them when viewing them within the InDesign CC Libraries window within InDesign or AI or from the CC library website. The problem happens when trying to drag or copy the object to a document.
The strange thing is that using the same library and library object, you can use the object in AI CC2019 and InDesign CC2020 but NOT in InDesign CC2019. Also, the problem doesn't exist if you happen to be the original creator of the library. None of the team's permissions have been changed. They have checked that their CC app is still syncing. I even logged out of Adobe and logged back in. That didn't help.
Most of our team can not update to CC2020 right now because it would disable other aspects our our workflow. Some of our deliverable will not work unless they are CC2019. CC202 has been tested and will not work. So we have to stay with CC2019 for now.
It feels like something got broken on Adobe's side of things since this happened right after the CC app update a few days ago.
