My site was getting a lot of impressions and clicks from being cited in AI Overviews. A few days ago(26 October), traffic suddenly dropped by about 90%.

What I've checked in GSC:

- The affected pages are still crawled and indexed

- Average position is still top 5

- The drop is in clicks and impressions, not rankings

So it looks like we lost the AI Overview citations rather than organic rankings but I can't confirm that from GSC alone.

Has anyone else seen something similar recently? Was there a Google update or AI Overview change I missed?
