I have an iPhone X with iOS 12 installed. I have location services turned "on." I am trying to upload about 1,000 photos to a Dropbox folder. Other apps like Google Photos will just upload in the background. There seems to be no way to get Dropbox to do this, so I have to keep waking up my phone. Is there a workaround? Is this a bug? Frustrating, as this will take days.
