I host my own website with a simple custom app that uses the Shopify JS Buy SDK. As of today the buy buttons no longer appear on product pages. Instead the JS console in Chrome shows a number of errors.
I suspect this is related to using an old version of the SDK with deprecated callbacks, but the upgrade instructions are inadequate. For example the Github repo has a guide for upgrading from v0 to v1 but the latest release is v2.20.0 so the documentation itself is out of date. I tried to hire some “Shopify Experts” to upgrade my scripts but did not find anyone who seemed qualified.
Here’s a screenshot of the JS console in Chrome.
