Hi @candaceavsa,
Here’s a brief explanation of the two features in question and how they might be impacting your video playback:
- Optimize Critical CSS Loading: This feature enhances your website’s load time by ensuring that only the CSS necessary to display the initially visible part of your website is loaded first (above-the-fold content). While this can improve speed, it shouldn’t typically affect video playback as it deals with style sheets rather than scripts.
- Defer Non-Essential JavaScript: This aims to speed up the time it takes for your site to become interactive by delaying the loading of JavaScript files that are not critical to the initial page display. However, this can potentially interfere with video playback if the JavaScript required by the video player is deferred.
To pinpoint the exact feature causing the issue, I suggest re-enabling these features one at a time. Start with “Optimize Critical CSS Loading” and test your videos. If there’s no issue there, move on to “Defer Non-Essential JavaScript.” This methodical approach will help identify the specific cause.
If you discover that “Defer Non-Essential JavaScript” is the culprit, you can continue using Jetpack Boost and its “Optimize Critical CSS Loading” feature without a hitch, while keeping the JavaScript deferment turned off.
This should allow you to maintain the performance benefits of Jetpack Boost without sacrificing video functionality. If you need further assistance or have questions, feel free to reach out.
Best regards,
