To view all of your current Stories, tap your Profile icon at the top to go to your Profile screen. This is where you can add Snaps to Stories, manage them, see who's viewed them, or delete Snaps from your Story.
You can also view and manage all the active Snaps you've submitted to Snap Map — which can show up on Snap Map and elsewhere around Snapchat.
If you're looking for how to view other peoples' Stories that you follow, you can still view all your subscriptions in one place by tapping the 'Subscriptions' or 'Following' button under your Friends' Stories.
