Revert one-page checkout back to 3-step checkout, and abandoned email flows for one-page checkout

The update in checkout has killed my conversions. We are spending anywhere from $100-300 per day in advertising and I cannot afford to do that when we aren’t getting orders. We had a fantastic September with great momentum rolling into October…as soon as I got the email about my updated checkout, within a day or two I noticed a sudden decrease in conversions. We already have a million things going against us in the advertising space, we don’t need our own websites working against us. We insist we get the option back to have our previous checkout options. This isn’t something we should have to upgrade to do, I’ve had it for years already. Someone from Shopify, please respond this, and let us know what your corrective plan is. We are rolling into the biggest season of the year, and this will cause all of us to take massive hits in Q4. If This isn’t addressed, I will find a platform that is working for us.
