Thanks for the link. This worked. Note I did not have to delete the photos, I just had to change the rating and also gave them e "pick" flag: In the My Photos area in the left pane, select the All Photos album. Switch to the Square Grid view ( ), which displays photos as equal-sized thumbnails along with their flag status, sync status, and rating. While holding down the Alt key (Win) or Option key (Mac), click the cloud icon ( ). Lightroom CC now displays only those photos that it's trying to sync. Press Ctrl+A (Win) or Command+A (Mac) to select all the photos displaying in the grid and then do any of the following: Delete the selected photos by choosing the Edit > Delete option and then add the photos in Lightroom CC again. Apply a flag or a star rating to selected photos. The syncing issue should now be resolved. To check the sync status, click the cloud icon ( ) at the upper-right corner.
