Hi there,
Thank you so much for the ⭐⭐⭐⭐⭐ review — we really appreciate you taking the time to share your experience! Great to hear that Jetpack Boost has improved your site’s speed! On the free plan, it’s generally a good idea to regenerate it after making design or content-related changes — for example:
- Changing or updating your theme
- Adding or editing posts and pages with new layouts or blocks
- Installing or updating design-related plugins
- Updating WordPress core
You can read more in When to regenerate Critical CSS.
If you’d prefer not to think about it at all, the paid plan includes automatic Critical CSS regeneration, which removes that manual step entirely.
Thank you!
