It sounds like there may be an issue with the coupon code being automatically applied for some customers on Safari. Here are some steps you can take to troubleshoot the issue:
Check your discount settings: Make sure that your discount settings are set up correctly and that the coupon code is not set to be automatically applied. You can check your discount settings in your Shopify admin by going to Discounts > Edit discount.
Test the coupon code yourself: Try making a test order using the coupon code in Safari and see if the coupon is automatically applied. If it is, then there may be an issue with the coupon code settings or with Safari specifically.I hope this helps
I know this is old, but I just ran into this and have received multiple screenshots from customers who have not entered a code, but they can’t checkout because the code can’t be applied. I had to delete all my discount codes. Did you ever find a solution.
The actions I was doing just before were,
(1) Create a DISCOUNT for a certain amount of discount on an order. Specify only users who have not yet purchased.
(2) Next, duplicate the discount created in step 1 and create a discount with a percentage discount.
(3) Confirm the application with the discount url created in step 1.
(4) Confirm the application with the discount url created in step 2.
The browser I was using was the Arc browser on my Mac, but the coupon was applied even in Incognito mode, and even though I changed the browser to Safari and did not enter the code even in Incognito mode, the coupon in 1 was applied.
I changed the device and checked the Brave browser on my phone in Incognito mode, but the discount of 1 was still applied. As you can imagine, my blood ran cold at that point.
As others have written, deleting the discounts took care of the problem, but in my case, I only deleted the 1 and 2 discounts I had just created, not all the discounts. I think it may have been eliminated since 1 and 2 were the only discounts for certain amount or % discount. The other discounts, such as shipping discounts, were not deleted. Discount was not applied to the checkout screen.
Of course, the coupons I created are of the code type that must be entered to be applied, not automatically applied.
I am using a modified version of the Dawn theme. It is based on a slightly older version, but the relevant parts were the same as the latest version.
I am afraid to create a discount and hope a permanent solution can be found.
When I added the discount again, it did not disappear from the store even after I deleted the corresponding discount.
However, I discovered that I could get rid of the persistent discount display by adding a line break to the store theme file and having the theme itself rebuild. In any case, it should not be a browser-side issue.
