For my reports it is very important for me to be able to consistently distinguish YouTube campaigns from the other types of campaigns. What works most of the time, but not all of the time is to add a filtering predicate on AdNetworkType2 and using the values ['YOUTUBE_WATCH', 'YOUTUBE_SEARCH']. I then use the other 3 options ('SEARCH', 'SEARCH_PARTNERS', 'CONTENT') to bucket the rest of the campaigns as non-YouTube. However, occasionally, YouTube campaigns will only show up when filtering for 'CONTENT' and not for either YOUTUBE_WATCH or YOUTUBE_SEARCH. I was hoping there was a more definitive strategy I could use that would categorize campaigns as YouTube or not accurately every time.
