Click on Settings in the bottom left corner of your Shopify Admin
Click on Checkout, then click Customize
Click on the page drop down in the top middle, then select Thank You.
Click on the Sections icon in the top left, then click Add app block under Order details. (Sometimes this will be at the bottom of the left navigation)
Add the app block for Recheck Order Edit. If you're also using Recheck for upsells, then also add the block Recheck Post Purchase Upsell
We recommend keeping the Recheck Order Edit block at the top of the Order details section so it's easily visible to encourage customers to fix their mistake. You can follow this up with the block for Recheck Post Purchase Upsell.
Now navigate to the Order Status page.
Similar to steps 5 & 6, add the app blocks under the Order status section.
Click Save in the top right corner. And you're done!
