Payments + Shipping & Fulfilment
,

Topic summary

A merchant reports multiple autofill and address caching problems with Shop Pay during pickup order checkout, specifically on Google Chrome.

Key Issues:

  • Shop Pay autofills both billing and shipping addresses with user’s personal information instead of leaving shipping blank or using the store’s pickup location
  • Guest checkout leaves pickup address blank incorrectly
  • Firefox requires page refresh at payment step for pickup address to populate
  • Switching from pickup to shipping causes the pickup location to remain stuck in the shipping address field
  • Changing between pickup locations doesn’t update the address correctly

Temporary Workaround:
Deleting the Shop Pay account, clearing cookies, and refreshing the page resolves the issue.

Seeking Solution:
The merchant asks if there’s a Shopify setting or checkout configuration to prevent this autofill/caching behavior and force correct pickup address updates without requiring users to clear data or delete accounts.

Hi Shopify Community,

I’m experiencing an issue with Shop Pay when placing pickup orders (PU) using Google Chrome.

**Issue Description:**1. If a user has a Shop Pay account and selects a pickup order, Shop Pay autofills both the billing and shipping address with the user’s personal information, instead of leaving the shipping address blank or assigning the store’s pickup location.

  1. If the user checks out as a guest, the pickup address remains blank, which shouldn’t happen.
  2. On Firefox, the issue doesn’t occur if cookies are cleared before testing, but when reaching the payment step, the pickup store address doesn’t autofill until the page is refreshed.
  3. If a user starts checkout with pickup and then switches to shipping, the previously selected pickup location remains stuck in the shipping address field.
  4. If a user switches from one pickup location to another, the first selected pickup location remains and doesn’t update correctly.

Temporary Solution Found:

If the user deletes their Shop Pay account, clears cookies, and refreshes the page, the issue disappears and checkout works as expected.

Question:

Is there any Shopify setting or checkout configuration to prevent this autofill and caching issue? Is there a way to force the correct pickup address to update without requiring users to delete cookies or their Shop Pay accounts?

Any advice or suggestions would be greatly appreciated. Thanks in advance!
