Hi,
My store has the random “Too many attempts” issue when customers want to checkout. I always have to reply their email to tell them to clear browser cache or use incognito browser. However, it affects a lot to my conversion. Is there any chance shopify can fix this error in the backend? I am using Rebuy for Smartcart and Reconvert app for Thank you page. However, I did try to remove the two apps for sometimes but the problem still happened.
