I've been trying to use the share to Flickr extension built into iOS 8 on my iPad Air 2, but I can't get it to work. I've logged in (and out and in again) a number of times and even switched accounts, but sharing to Flickr never does anything on my iPad. Also I can't see my existing groups. They won't download. Sharing to other services, like Vimeo works fine. Also the Flickr app works fine, but not the Flickr sharing built-into iOS. Sharing to Flickr works fine on my iPhone, so it's not my Flickr account. I can't figure out how to fix this. Any ideas?
