There was a moment in time when Instagram use to show this disclaimer "You're all caught up with the posts". You could still scroll below that and it would show you algorithmic content as it always have if you choose to view it. However I don't see this feature anymore and it's gotten worse with pure infinite slop. I really appreciated that cause every time I opened the app, saw that disclaimer I would instantly close it and go about doing other things. I wish they just kept simple stuff like that around but I guess that doesn't help their metrics.
