I upgraded my Lightroom Classic CC and tried to open my default catalog, but had to upgrade the catalog in order to open it in the updated version of CC.
I have tried this with several updated catalogs, but all of them have no info in them when I open them, they look like I have created a new catalog with zero info in them.
Is anyone experiencing similar issues?
Your title mentions 'does not sync'
Your text refers to opening a catalog.
What exactly is it you are asking?
I can open the catalog in Lightroom Classic CC, but once it is open the updated catalog has no images or info in it,
also once updated the file info of the catalog states that it has just been created.
My question is how can I open the updated catalog in Lightroom Classic CC and have access to all the info previously stored in it.
