1. You are using external themes that are not from Shopify: #
Often the file cannot be shown automatically in the cart section, because your theme does not support this.
Leave us a message for investigation.
2. You are using an OS 2.0 Theme and you forgot to add the App Block #
OS 2.0 is very new to merchants. Often merchants forget to add the App Block in the customizer to activate the Textbox App. Go to Online Store -> Customize
3. You are using multiple apps and they are conflicting #
Sometimes it’s very hard that everything is working smooth. Some merchants install a lot of apps to customize their store. With every app more, your theme code will changed too. If you are using multiple apps for high customization like
Bundle Apps, Live Preview Product Options or Page Builders it will maybe not work by automatic. Often one app overwrites the other.
