@GaPatriot3 ,@Administrator - Same problem on my Desktop from the beginning of AU in 2021. Originally, I stopped using AU because of this same problem, couldn't scroll past last 12 - 15 posts.
Now to get around this AU issue, I just bookmark major posters and go to their pages daily and scroll down and get tons of info. I brought it up before, no response > thank you GA for posting the vid, maybe AU will finally fix the issue.
