Connecting the Shopify app does not automatically change your live theme. Complete the two storefront steps from the Composerie setup check.

1. Switch Composerie on
Select Open theme editor in the first row. Shopify opens the app-embed context for the current theme. Enable Composerie and save the theme.
The app embed is what loads Composerie into your theme at all. Keep it enabled even when a product uses Full page mode.
2. Add the personalization block
Select Add block in the second row. Shopify opens the product template and prepares the Composerie block in the main product section. Place it near the product form or main purchase action, then save.
3. Recheck the setup
Return to Composerie and select Recheck. The setup dialog verifies the active store and reports the current theme state.

Why are there two steps?
The app embed loads the storefront integration; the block gives the product template a visible place for personalization.
Which theme is changed?
The Shopify links target the store's current theme. Verify the theme name in Shopify before saving when you also maintain unpublished themes.
Why does Recheck still show a problem?
Confirm both changes were saved in Shopify, then wait briefly and run Recheck again.
