If you change your Shopify theme after you add the Experiences app to your store, you may need to take a couple of steps to ensure that your experiences show up on your store. If you experiences are not bookable or not showing up on your store, please try the following:
Log into your Shopify admin
Navigate to the Experiences app dashboard
Click on the settings icon
Scroll down to the bottom of the page
Click on the "Reset all templates" button
If you had made customizations to the previous Experiences app theme file, you can go into your previous theme files, find the product.experiences.liquid file, and copy the code contents into the new theme and overwrite the product.experiences.liquid file there.
