The hashtags set on your Gallery will automatically post to Facebook and Twitter. Instagram has a more protected sharing platform, so we're unable to automatically post your hashtags there. Instead, we instruct your guests about which hashtag to use when they receive their photo.
When working online, update your hashtags from the gallery panel in app, or from the "Basic" panel on your gallery settings.
When working in app, update your hashtags after tapping on the "manage galleries" button within the Gallery Panel.
Once within the "Manage Galleries" view, tap on a specific event to bring up management options.
