When I complete a slideshow and use the 'Share' option, there is the facility to upload the slideshow to either Facebook, Flickr or Youtube. As I already have a Flickr account I decided to upload it there. I get as far as selecting Flickr and entering a title, description and keywords for my slideshow, but when I click on 'upload' I get an ugly-looking screen (see attached) saying I am using an unsupported browser. This is puzzling because I am using the latest version of Chrome on my W10 Pro laptop (which also obviously has Edge and IE 11.00). When I try to continue anyway, I then get a message saying "An error occurred while uploading. Please try again later."

Can anybody help? Thank you in advance.
