For some reason the data for the analytics on my account does not populate or display in the overview section. When I go check on the pins I have created it shows that they have views and saves but that information does not seem to be tracked correctly.
Looking at your screen captures, this happens for my account occassionally. One of the following usually worked to resolve the issue for me:
1. Log out, log back in on both desktop and mobile.
2. Update Pinterest app on mobile.
FYI: Impressions and other metrics can take some time to show. Also, real-time metrics are estimates and subject to change.
