If Order: Subscription > Active Subscription Warning Popup is on (it's on by default), the Subscription signup page shows a modal when you already have an active, auto-renewing plan: it names your plan number and its next renewal date, then asks whether you want to Create a New Plan or Wait until Renewal. Separately, the A la Carte ordering page shows a different nudge if you already have an active subscription — it asks whether you're trying to place a new order for A la Carte or actually meant to select meals for your subscription instead, and links you to My Meals. Both are meant to stop customers from accidentally double-ordering.
