Has anyone else noticed Performance Max campaigns seeings a random spike in impressions? The campaigns I've been seeing this happen to have been running for over a year, regularly maintained (exclusions, adjustments, etc), usually performing well. Additionally, some of these campaigns will normally see a couple thousand impressions daily and randomly I'm seeing them go close to 10x the normal impressions.

Looking at Channel Performance its primarily YouTube impressions. I usually export this list to Claude and then have it group the videos/YouTube channels into groups and a bulk of it is international channels/videos, very irrelevant to the business I'm advertising.

Noticed it more the past 2 or so months and wondering if anyone else is experiencing the same.
