If changed settings are not applied on the online store, check whether you saved, whether you are viewing the correct theme and page, then the browser display, in that order.
If you changed "Customize the table of contents," select "Save." Also select "Save" if you changed the app block or app embed in the theme editor.
Confirm that the theme where you added the app block is the same theme you open in the online store. If you are checking a product, page, or collection, also confirm that you are on the Regular plan and that the app block is on that template.
Custom Liquid and per-block title and button labels are applied on the Light plan and higher. On the Free plan, the fields appear, but the input is not applied.
After you save, reload the target page. If the change still does not appear, try the following.
(1) Hard-reload
Reload with Ctrl + Shift + R on Windows, or Command + Shift + R on Mac.
(2) Check in a private window
Open the target page in the browser's incognito or private mode.
