I had this happen to me twice now. Once back in May, I tried to upload some photos taken up north and a couple of them said "You can't share this link" in place of where the thumbnail of the photo is usually. It has a triangle with an exclamation point inside of it. There is nothing bad in the photo, it was a mountain and a sky. I tried cropping the image, resizing the image, and converting it to PNG using Photoshop. But I am still receiving that "You can't share this link" message whenever I upload those specific photos. Fast forward to today, I tried uploading a photo of a field that I took. Same error message. Tried the same steps to resolve it. However, the same message still persists. I received an "Oops!" error message on a couple photos of my wife and I posing in our yard today, but converting those to PNG worked. It is not working for the ones getting the "you can't share this link", however. A Google search does not turn up any hits pertaining to photos uploads. Most are sharing links or links to old photos and even those do not have very many results. None of the results pertain to actually uploading photos except my help center question regarding it which has absolutely zero replies. Why am I not allowed to upload some photos that I took?
