For some reason our portal started flashing every second (just in the video window as everything else looks normal) or so with the size of our interstitials. The strange part is that the flashing picture that appears is actually from the background image that I created. Any guess as to what might be causing this.
I've re-verified everything and nothing has changed with the exception of additional deployments with no major modifications. I've tested everything I know to test, but no luck thus far so any direction would be appreciated.
