Occurrence:
User tried to upload a project to Central, it failed stating some other program was using it. The local copy no longer shows up in the Central projects tab. How do I get this updated project onto Central?
Resolution:
You'll see the buttons to import an open project to Central, on the 'Central Projects' tab. If the project previously resided on Central, then the software will ask if you would like to add this to an existing project, or create a new one (as a new branch).
To import the currently open project to the same branch, use the second publish button in the lower left of the window where it says 'logged in', and then click 'publish'.
Root Cause
Publish failed due to another program holding on to the project files (most likely sharepoint or onedrive real time sync).
