In the near future, we’re going to release a new version of the plugin that will allow you to load things the version 10.5 and earlier way with a simple checkbox.
Fundamentally though, it’s a caching-based problem that you’re having and not something with the code of 10.6 approach. Perhaps you can try the following if you eventually wish to use the new approach:
1) Activate version 10.6 of our plugin (linked to above)
2) Turn off Jetpack’s Javascript Minifier if you have it turn on
2) Also, clear all cache in any of your caching plugins of course.
3) Please also clear any CDN caching as well. Apparently when caching <b>and</b> Jetpack’s Minifier are turned on, issues can occur: https://jetpack.me/support/getting-started-with-jetpack/known-issues/
