Add to Cart broken after installing Conversion Plus Pro

[SH_Support]

We have been using PreOrder Now WOD | PreSale app for awhile and everything worked great. We installed the Conversion Pro Plus app to be able to to delete products from carts after a certain amount of time, but since installing CPP, any product that is tagged for the PreOrder app cannot be added to the cart. Any suggestions would helpful.

Hi there, @SH_Support. Thanks for taking the time to reach out to the Shopify Community with your app and 'add to cart' functionality issue here. My name is Imogen. It's good to meet you!

As this issue appears to be the result of integrating a third party application with your store, you should reach out to the third party app causing the issue for support in resolving it if you suspect their app is the cause. As the application is third party and not developer by Shopify, we won't have any insights on what sort of coding changes should be made to address the issue (Shopify Support Staff are also not trained on coding) so connected directly with the developers of the app should be your first stop in having this resolved. You can connect with their support team by clicking the 'get support' button on the bottom left of their app listing page.
