I'm noticing an issue in Lightroom Classic CC, in the Library module, when navigating between Collections. This is with the 8.2 release on Windows 10 1803, although the issue was present with 8.1 as well.
If I am viewing a collection that is synced with Lightroom CC, and then select a published collection, the grid view in the published collection does not show the groups by publish status (Published Photos/Modified Photos to Re-publish/New Photos to Publish), and hitting the Publish button does not publish any new photos in the collection (e.g. export and upload to Flickr).
I can work around this by first going to a non-synced collection, or a folder in the file system view, in which case the published collections work as expected.
It is not a work-stopping issue, but it is annoying, especially as I make more and more use of Lightroom CC syncing.
