Elle here from Shopify's Social Care team.
I took a look at your site unicorniia.myshopify.com and I was able to see the return to cart option within the checkout!
If you still can't see it on your end, could you please let me know what browser and device you're using?
Looking forward to hearing from you! :)
Same issue using debut theme in Chrome browser. No return to cart or continue shopping button, just a continue to payment button. When I go into admin it shows the return to cart and it also has the header linking to the home page which is nonexistent when I test in Chrome Incognito browser.
How can I get both things working: a) header or logo to link to home page, and b) a return to cart or return to store button?
We also have this problem.
It seems, that Logged in users don't have any options to return to the shop even after the order is completed. EVEN IF IT'S COMPLETED!
A new, anonymus user can go back, but why can't a returning customer? This makes no sense. No return to shop button, no link on the logo on top. The user is locked in on the thank you page. Only by editing the url or closing the page / tab can they leave this page. Why?
I've seen the issue on one of my websites, but think it is something to do with a pricing app. If I'm using a customer which changes prices (customer tag/wholesale app) the return to cart link is not there, but on the same site using a customer without special pricing (no customer tag), the return to cart link shows.
