Hello,
Sorry to say that but we have not officially tested the mentioned “Cart Flow” plugin with the Theme yet, nor it is included in the compatible list confirmed from our end on the item page.
So, if you want to use it you can try it out at your own risk. If some issue occurs then, you can consult Plugin Support in this regard because we don’t provide Support for third-party plugin issues, as it isn’t included in the Item Support Policy. Hope you can understand our limitations here !
Moreover, generally, the Plugins which work correctly with the default WordPress Themes will eventually work fine with the WoodMart Theme too.
Best Regards.
