PS I've now had another look at the synchronization process. There is no download from the web of ny photos shot with my phone or iPad. to my computer. Uploading new photos from my computer to the web works fine. Also, metadata changes on my computer seems to MOSTLY upload fine. However, there remains five images that stalls in uploading. When I remove these images from the catalogue, five new images are listed as in transfer to the web – but nothing happens. They just sit there.
