This is an absolutely excellent video - I use iCloud, google photos and after issues exporting my original images and videos (not resized - painful to export from Google photos), I am 100% going to add Dropbox to the list. Great video - concise, logical and covers a bunch of questions I had about Dropbox for a 'real' backup of Dropbox.
I am happy to help and yes I know the pain of trying to get photos out of Google Photos! It is a balance between fancy app features and being able to get your photos easily 😁
You won't be able to do that in the Dropbox Photos area, but if you use the App on your PC or Mac so it appears in Explorer or Finder you can use the normal file information to Tag then and sort them. 😁
