Keep subscription intent intact from product page to cart.

PlanLatch repeatedly verifies Shopify subscription purchase paths on desktop and mobile, then reports the exact state that broke.

• Subscription-specific. Verify widget visibility, form state, cart allocation, one-time cleanup, and variant changes.
• Minimal access. Read products only—never customers, orders, payment methods, or subscription contracts.
• Evidence-led. Every incident includes the affected product, viewport, failed state, and suggested next check.
