I mainly used mobile at the time, but until 2019 I used tumblr on an android phone, and when I would go to a post on someone's blog (via recommended posts, tags, etc, rather than from scrolling there from the beginning), I would then be able to click it, and continue vertical scrolling such that the posts that were made/reblogged directly before appeared in order as if you opened the blog the moment it was posted/reblogged.

When I started using apple I didn't have that feature, and later on there was a point when I checked the tumblr app on the old android phone and the feature was gone from that too.

I feel like I might have a false memory because I don't have a memory of people complaining about the loss of this feature, but I distinctly remember missing it. still, if it was around, is there a way to get it back, at least for your own blog using a custom theme or something? Thanks!
