When I first used Dropbox a few years ago, as soon as I took a photo on my androad phone the photo would be uploaded to my dropbox and synced to my PC. Nowadays I can take a picture on my android in the home (with connected wifi) and when I hover over the dropbox icon on the PC it states "Dropbox Up to date" it can be hours before the system decided to upload/Sync. Is there a way I can force it to upload/sync now please?
