Sorry for the late response as I thought AG would inform my email. Anyways, I hadn't enabled the annoyances filter but have enabled all 4 filters now and it doesn't seem to help, unfortunately. The annoying notification still pops up.
It can be eliminated by giving in to its demands of disabling AG filtering bit the website then loads slowly with all sorts of ads and stuff.
However, what you should do is try disabling some filters one-by-one and forcefully refreshing the webpage (F5 on Windows) or clearing the cache and loading the page again. Maybe you can narrow down which filter list could be causing this detection.
