Hi Patrik,
I have received the requested information privately. Upon investigation, the campaign Id you mentioned is indeed a TrueView for Reach campaign subtype. This type of campaign is currently not supported in the AdWords API. This is the reason why it does not show in your reports.
Let me know if you have further clarifications.
Hi Suk Kim- Could you confirm if you are also encountering the same issue as Patrik wherein some of your campaigns do not show on your reports? If yes, this could be because some of your campaigns could have a campaign subtype of TrueView for Reach as well. This is currently not supported in the AdWords API.
If you have a different concern, could open a new thread for better communication?
