Missing cart button

My app is not showing the Add to Cart button and the Cart icon. What is the problem?

If you use the WooCommerce solution and cannot see the Add to Cart button and the cart icon on your app, your app has switched to Catalog mode. Purchasing will be restricted in the catalogue mode.

Enable the User registration toggle by navigating to Access > Login from your WooCommerce app dashboard. Click on the gear icon at the top right of the "Login" screen.

Click on the SAVE button after making changes.
