Hi,
On July 26th, I linked my Google Analytics and AdSense accounts by following the official directions (https://support.google.com/adsense/answer/6084409?hl=en).
Starting the same day, I experienced the two following issues:
- drop in the pageviews, both of Google Analytics ('page_view' event) and Google AdSense.
- boost in the 'Unassigned' traffic acquisition of Google Analytics, subtracting traffic to 'Organic Search'.
Similar experiences are welcome.
