I need to vent about checkout broke. This has been driving me crazy.

What Changed

The Deadline

  2. The reality is that most merchants do not know this is happening.
  3. Based on Shopify changelog, many stores are affected.
  4. I switched on a test store and the results were mixed.
  5. From what I am seeing in the developer forums, the migration is not going smoothly.

Cost Breakdown
