There are a number of reports that the performance reports, both for Google Search and the Generative AI features reports, are showing a decline in impressions and clicks (AI report does not show clicks) starting around August 12th and 13th. This seems like a bug because the drop seems to be super widespread.
Update, Google has confirmed the issue - the story is updated below.
Here is one chart showing the Generative AI performance report impressions dropping off a cliff:
Here are some of those reports:

Heads-up, I'm hearing from site owners about a weird drop in clicks starting around 8/12 in GSC that might be a bug. Visibility reporting is stable and analytics shows no drop. Just a heads-up if you are seeing a weird drop starting 8/12 but visibility is still strong + analytics shows no drop. Stay tuned.

Seeing a decline in impressions in the Generative AI report in GSC since Aug 13th/14th. Coincidentally, we seem to hace drop our number of citations. We wonder if Google changed something in AIOs and has not been reported?

Anyone else seeing a sharp drop in Google Search Console’s AI impressions around August 12?I’m seeing almost every client project show the same pattern: weeks of growth, then a sudden cliff-edge drop within a couple of days.
Because it’s happening across multiple sites at the same time.
Here is Meenka's chart:
A thread on Google Webmaster Forums says:
In Google Search Console's Generative AI Features report, I'm seeing a very large decrease in impressions in the past 2 days (starting 8/13).Is anyone else experiencing similar, or know of relevant changes made by Google recently?
Here is that chart:
Dave Smart replied to that post saying:
I am seeing a similar pattern across a number of properties, so I suspect there's perhaps partial data for some days, rather than something specific to your site / property.I'll escalate it, just to set some expectations, I can't give a timeframe of when or even if we'll hear something back, but I'll make sure to update you if I do.
Are you noticing this in both your Search performance report and Generative AI performance report within Google Search Console?

Update: John Mueller confirmed the issue on Bluesky and wrote:
Hi Juan, we're aware of this issue and working on resolving it. This is just a logging issue and not representative of visibility changes in Search. We're adding an annotation in Search Console to let folks know about this in the near future.
Google added to its data anomalies page:
August 13 (Generative AI in Search)A logging error caused a decrease in impressions on the Generative AI performance report in Search for data starting on August 13, 2026. This issue affects data logging only and is ongoing.
Update 2: Google also posted this on the data anomalies page a day later:
August 13 (Discover and Generative AI in Discover)A logging error caused a decrease in clicks and impressions on the Discover performance report for data on August 13, 2026. For properties with access to Generative AI features in Discover, this error also caused a decrease in reported impressions. This issue affects data logging only.
Update 3: It seems to be fixed going forward:
Seems like the Google Search Console performance report for generative AI search features is fixed - seems to have bounced back on impressions - old story at https://t.co/zu3dxJViGv pic.twitter.com/mf5uEyJ8IR

Update 4: On August 31st Google noted it fixed the Search generative AI report data that was missing - Google actually fixed it a while ago but just added a note that it was fixed today:
