Hey there, @CamperKelly
When I take a look at your site I am unable to replicate this issue. I tried it on Chrome and Safari, and Incognito (chrome) and private window (safari). This is what I'm seeing https://screenshot.click/20-09-boh37-e4wp5.png. Do you still see the express checkout buttons on your checkout page? Are you seeing this when you visit https://campsites4u.com/ directly and click through your checkout?
I had a look into the forum link that you sent, and the original poster was referring to the pop-up notification when customers click 'add to cart', which can be removed from their theme settings. You can follow the steps in Tim's response if you want to remove it. Debut has never had a cart drawer. If actually want a cart drawer, I recommend starting a new thread within the community or sharing a Shopify Expert.
Looking forward to hearing from you,
Could you please share links to your store so that I can take a look and investigate to see what is going on?
Thank you! Could you please clarify what theme you are using and can you confirm that you followed all of the steps and not just adding the code to your style.scss?
All the Best,
Thank you for confirming, Florence is not a Shopify supported theme so I would be unable to guarantee that the tutorial shared here would work. We are not trained in altering third-party themes, as their code is not written by our team we cannot provide support for them. It looks like Florence is an OutoftheSandbox theme and you can request support from them directly here.
All the Best,
