Like most folks are reporting - my Meta ads performance has suffered tremendously in the last 30 days.
Looking through Stape analytics for my container, it would seem ad-blocker recovery percentages plummeted at the same exact time my Meta ads performance did. From a 44% recovery rate (90 day average) down to 7% recovery rate (last 10 day average).
I can’t see any issues with your configuration. I’ve also tested it with several ad blockers – they don’t block the requests, and everything works as expected.
Perhaps you’ve made some changes to your website or your containers?
It seems to me that it was actually working incorrectly before. ~40% of requests from ad blockers is a very high figure; this is usually only seen on sites with a technical audience (sales of microchips and computers, specialist forums, etc.).
So it looks to me that it’s working fine now. It’s also clear from the first screenshot that you used to have roughly the same amount.
So it looks to me as though this spike has been caused by some changes to your tracking settings (or GTM) or, perhaps, on the website.
