You want me to design or develop a feature concept related to Snapchat's older versions (e.g., a "Classic Mode" feature that brings back the old design or functionality).

Allow users to toggle between the current Snapchat UI and a simplified "Classic" interface reminiscent of Snapchat ~2014-2016.

Snapback Mode

You want to download/install an old version of Snapchat on your iPhone (e.g., because the new version is slow, has bugs, or you dislike the UI changes).
