The feed is where you can view all of your notifications and insights. The content in this feed can vary depending on the notifications you've set.
Here is a view of a typical feed. Notice the notifications that have triggered.
Insights will be outlined in blue. Insights look for patterns in the data that aren't always obvious.
There could be a notification or insight you wish to save for later reference. You can do this by archiving your notifications/insights.
In order to archive a notification/insight all you need to do is swipe left on the desired notification/insight. Tap the blue archive button and now your notification/insight is saved.
You can access your archived notifications/insights by tapping the white box icon on top right of the screen.
If you wish to clear your feed of no longer useful insights or notifications you may delete them.
Do this by swiping right on the notification/insight you wish to delete.
Tap the red delete button and your notification will be removed.
