And do not even try to edit your local desktop photos (desktop uploader will not recognize at all) or try to delete local photos. Google photos only works OK if you ONLY use your mobile phone for taking photos. If you have an normal camera like e.g. a DSLR and want to sync that with Google photos: Forget it. You will only have a lot of more management work with Google photos. Google photos is again a dead end for your data. What we need is a good two way sync for the desktop and more management possibilities in Google photos (because there are NO management features). If you look at Lightroom and their cloud sync (if you have an Adobe Cloud subscription): Adobe is lightyears ahead in syncing. Google clearly does not care at all about the desktop.
