White Elm review for PreOrder Now Backorder WOD

Absolutely no support. Had my products on pre-order and when I took them off pre-order, one did not change the CTA button back to "add to cart". It is still stuck on "pre-order now". I've reached out to support several times with no response. I even deleted the app and it still remains. There is no way for me to change back to "add to cart" and they refuse to help, even with Shopify opening a ticket. If you don't want your website code messed up, I do not recommend this app.
