As you know, when you're in the camera roll on an iPhone you can select one or more photos from the "send" button and take various actions. One such action I have is "Save to Dropbox", but this is only available until I select more than one photo.
Beyond that, I can click "Save to Files" and one of the options is "Dropbox"; however, it's grayed out/disabled -- regardless of whether one photo or multiple photos are selected before clicking "Save to Files".
So how do I save multiple files from the camera roll to Dropbox? Why would it not be possible using the standard method?
Note: I know that I can go to the Dropbox app and select multiple files to upload from the camera roll. This question is specifically about doing this procedure from the camera roll.
