There are reports that in some cases you can be missing some of your Google Ads data and campaign information when you use the Google Analytics 4 API in conjunction with Looker Studio and/or Google Sheets.
Diogo A. da Silva said on Twitter that if you are using the Google Analytics 4 API to report on or manage budgets with either Looker Studio and/or Google Sheets then some of your Google Ads campaign data may not be showing up.
Diogo also added that if you pause a campaign or delete a campaign, those will be removed from your GA4 reports.
Here is a screenshot showing this from Diogo (click to enlarge):
Ginny Marvin, the Google Ads Liason responded, saying she will pass this along.
Here are those tweets:
Thanks, I will pass this along to the team.
