Our app is compatible with a huge majority of the themes in the market. It will be updated automatically when you publish a new theme.
If you notice that after publishing a new shop theme the app works incorrectly, please don’t hesitate to contact us.
However, if you are using the “Add to cart” button styles for the pre-order button then you should update them after publishing a new theme.
Go to Design page
Click Update preview at the bottom of preview section
Click OK on the pop-up
Check that the preview of the pre-order button has been updated with the appearance of add to cart button. If you have any problems, then you should contact support.
