Hey, not sure when this regressed, as I'm browsing Lemmy rarely, but it used to sort of work when the experimental features was added, but it broke again in recent months.
Swiping the post left, to go to the next one, bumps you back to the list of posts.
Swiping right on the post seems to work, but it kinda goes back in the history, as opposed to the list of posts.
Amazing, thank you! I can confirm it's working again as expected.
