The test build in question experiments with side-to-side swiping and tapping, making the feed work like its Stories. The pulled update even had a note that read “Tap through posts, just like you tap through stories.” https://twitter.com/TaylorLorenz/status/1078312647391674369 In a way, it’s a fortunate thing that it was an accidental release of a test build and not an official rollout. It was clear that a fair number of people are not happy with the change. At least, that’s what Instagram head Adam Mosseri says. https://twitter.com/mosseri/status/1078322669307609088 If you’ve already gotten the update and would like the old Instagram back, then all you need to do is to restart the application.
