apps.liquid.Summary :
– This issue is related to the Horizon / Shopify free theme layout behavior
– It is not an app bug
– Dawn, Shopify premium themes, and ThemeForest themes work without any issues
– Following the steps above will resolve the problem
If you still face issues after following this guide, please share updated screenshots and we will be happy to assist further.
In the Horizon new update theme (and some other Shopify free themes), when you add an app block, it is automatically wrapped inside a Section container.
This Section applies automatic CSS and admin UI styles, which may conflict with the app’s layout. As a result, app content such as FlipBooks or iframe-based apps may appear squeezed, misaligned, or broken.
This is a theme-level layout behavior, not an app bug.
How to Fix the Issue (Solution)
Please follow these steps carefully:
1. Go to Online Store → Themes → Edit code
2. Open the Sections folder
3. Find the file named apps.liquid
– If the file exists, open it and paste the provided code into it
– If the file does not exist, create a new file named apps.liquid and paste the code into it
4. Save the file
5. Go back to Theme Customization
6. Add the app block again
After completing these steps, everything should display correctly.
