So, what does this process look like from moment to moment? Well, you'll start by opening your settings and finding the Snapchat app. Then, you'll clear the cache and wait for the process to finish. After that, you can reinstall the app and start fresh.
It's worth noting that this process will delete all of your snaps, so make sure you're okay with that before you start. But if you're looking to get rid of an update, this is the way to do it. You'll be starting from scratch, but at least you'll have the version of Snapchat you want.
