It'll be very useful if Tripadvisor could add to the Help Center how to do different things using the Apps and the mobile sites, in a different Mobile/App section.
Just a few that come to mind:
1. How to add a new listing with the mobile site and mention this is not possible using the App.
2. How do add photos to an existing review using mobile.
3. How to see your contributions using mobile and app.
4. How to access the full site from mobile (and that's not available through the app)
5. A general FAQ on what can be done with the full site but not on mobile and not on the app.
