I believe the user above was having the same problem I did. That is, until I deleted the old app and downloaded the new one. When you do so, it eliminates the problems listed above.
The new app runs much quicker than the last version, has all the same useful elements (notifications, ordering of threads by forum or date) and is my preference for accessing SDN, even when at home. The interface is easy to read and the site easy to maneuver around. An essential for any current SDN user or someone who wants reliable medical education information on the go.
