It appears that under certain circumstances the dashboard does not show the activity stream properly. Instead of recent updates, you see a message saying "There are no stream activities yet" or similar. If you have not posted an update in a while, the system fails to retrieve the activity stream for you to view. This issue has affected a couple of us so far, and we are working on a permanent fix. For now, if your activity stream appears to be empty, simply post an update message from your dashboard and you should see your activity return as normal. Again, we are working on a permanent fix, thanks for your patience!!!
