fullscreen/exitFullscreen tracking events were removed in VAST 4.0
WarningValuesIAB VAST 4.0 §2.4.1VAST 4.0, 4.1, 4.2, and 4.3
The `fullscreen` and `exitFullscreen` tracking event values were removed in VAST 4.0. Players conforming to 4.0+ will not fire these events. Use `playerExpand` / `playerCollapse` instead.
How to fix
Replace fullscreen with playerExpand and exitFullscreen with playerCollapse for VAST 4.0+ compatibility.
