Does Recharge Break Shopify Checkout? How to Monitor It

Recharge injects the subscription widget (subscribe & save vs one-time, frequency selector) onto product pages and hooks into the cart and checkout to carry subscription line items and selling-plan data through to payment.

• The subscribe/one-time toggle conflicts with variant selection. Switching frequency or plan can reset or break the Add to Cart handler for certain variants.
• The widget fails to load after a theme or app update, so the subscription option (and sometimes Add to Cart entirely) doesn't appear.
• Cart/checkout token mismatch. If the selling-plan data doesn't carry cleanly, the cart can error on the way to checkout.
• Mobile layout can push or hide the plan selector so shoppers can't choose a subscription.

Run checkout monitoring through the actual subscribe flow — select a plan, add to cart, reach checkout — on desktop and mobile, so a broken toggle or a missing widget is caught immediately. Pair it with app-conflict monitoring to catch the Recharge update that caused it.
