I am sending events to Google Analytics using Measurement Protocol. For a while (few days) these seemed to be showing up fine in both the Real-Time area of the Google Analytics Website and the Content->Events->Overview.
Now, they are still showing in the Real-Time page but the Content->Events->Overview shows no activity for over 5 days.
Would appreciate any ideas. Surely if they are showing up in Real-Time it shows that they are being correctly sent to the system?
