I use LR Classic, LRCC and Portfolio. All of them work perfectly. However, when I add some images in either LRClassic collections - synced with LRCC - or directly in LRCC, I didn't find the way to update Portfolio simply. The functions, "page reinitialize from LR" in Portfolio OR "send to portfolio" in LRCC don't upload the new images. I have no other way to delete the page and create a new one. Ennoying.
