So this issue has mostly cleared. It was a severe issue for days. (AG totally blocked News Feed and I had to disable AG for days). Yesterday, I turned AG back on and am using "Most Recent" on News Feed and AG is no longer blocking every item. After many page downs, there is some slowing as in the OP. No ads.For the past several days, same setup as before, AG is blocking my news feed on facebook.com.
If I'm in "Most Recent Stories" mode it blocks everything in the News Feed.
If it's in "Top Stories" mode it shows some things but it's quite slow and the shit its shows can be days old. And sometimes it shows nothing.
If I turn off AG for facebook.com,it works fine.. not slow, but lots of ads.
So AG is basically breaking Facebook. I realize that it's because Facebook changes things.
I haven't changed any of my AG filters or rules from before in this thread.
Did you modify the filters to make this happen?
