Separating out ad content from primary content IsThisAdContent? or PrimarayContent?.

True abandonment - leaving in the middle of quality content. Engagement vs abandonment. The final data point around user retention. Metrics that are artificially low because people reset the apps frequently. Intentional interruption towards re-engagement. The user intent to play something else. Number of re-buffering events compared to engagement; track watch-time Users will sit through lots of re-buffers if they want to see the content.

Exit before video start - captures the case where user does not get to playback. - strong case for adding it in. What about exit events ? sendBeacon - https://developer.mozilla.org/en-US/docs/Web/API/Navigator/sendBeacon
