Yes, YouTube lagging is common. Slow internet, a full browser cache, out-of-date browsers and drivers, or ad blockers are frequently to blame.
You can fix it by clearing the cache and cookies in your browser, reducing the quality of the video, updating your browser, or temporarily disabling browser extensions, particularly ad blockers.
When YouTube is experiencing delays, you can attempt to solve the issue by looking at your internet connection, removing the cached data of your browser, or setting the video quality to a lower level. Other ways to solve the issue are to update your browser and graphics drivers, turn off browser extensions and hardware acceleration, and close apps running in the background that are not needed.
In case the YouTube is not working, refresh the page, empty the cache, reduce video quality, or trying to disable extensions. Test your internet speed, change browsers or refresh the application. Reboot your device or router in case the problem is still there to play the content smooth.
If YouTube is lagging, check your internet connection, clear browser cache, and close unnecessary tabs. Lower video quality or update your browser and app. Restart your device or router to improve streaming performance and reduce buffering issues.
