2/ Thank you for the video. As we can see, you are using WPbakery, so please deactivate the Elementor plugin. If you are using a cache plugin, server cache, or CDN, temporarily disable them also. Go to Theme options > Speed Optimization > Remove Query Strings From Theme Static Resources > Off. When you edit Text element content, do this via the Text tab – https://prnt.sc/LXbujpTaz1BY
When you open the editor > element settings > Text tab at the first time, it can be empty, so close the settings https://prnt.sc/mckdxFre21Jm and open them one more time.
After doing this, clear the cache of the browser and check if changes can be visible.
Let us know the results.
