Someone shared a folder with me to add photos and there is no option to upload my photos into it. Only options shown are Download or Save to Dropbox. I should see an upload button but don't. Please help!
You need to get the person to share the folder with you not a shared link.
They havent shared it with you if thats all you see - they've sent you a shared link.
You need to ask them to share it to your Dropbox account so that you actually have to accept it
