You edited a rule, saved it, went back to checkout — and nothing changed. Almost always, this is caching rather than a broken rule.

Shopify caches rates per address

When Shopify has quoted shipping for an address, it reuses that quote for subsequent checkouts to the same address rather than asking the app again. Your rule change is live. You’re just not being shown a fresh calculation.
This is the single most common source of “my change didn’t work” reports. Before investigating anything else, retest with an address you have never used before.

Other things that look like caching

If a genuinely fresh address still shows the old behaviour, work through these.

The rule didn’t save

The rule form’s Save button stays disabled until the rule has a name, a priority, and at least one condition. It’s possible to make an edit, be unable to save, and navigate away. Check: reopen the rule and confirm your change is actually there.

Products need re-syncing

If your change involved Product Tag, Type, Title, Barcode, or Compare-at Price, and you also changed those values in Shopify, the app is still using its old synced copy. Fix: Settings → Products → Sync Now. Note that auto-sync covers only newly created products — edits to existing products need a manual sync.

Zones need re-syncing

If you added or renamed a zone in Shopify, sync zones from Settings → Shipping Zones.

A customization is overriding the result

Your rate may be calculating correctly and then being hidden or renamed downstream. Check: temporarily deactivate your customizations and retest. See Shipping Customizations Not Working.
