Page Error: "There was a problem with our checkout"

This is STILL an issue. It is not resolved. Shopify customer support told me that I should try going to the checkout on a cell phone. This is not how people do business in a wholesale setting. I am frustrated. The issue continues to be a problem and it is obviously not just for our business. A global solution is needed. I have no idea how many sales I have lost due to this but it has been going on for at least weeks and Shopify still doesn’t seem to be taking it seriously. Here is a screenshot from a few minutes ago.
