Issues that we face by using W3 Total Cache

Hey there! I would like to address some problems I faced when I integrated W3 total cache. They are listed below:
1. Site breaking randomly
2. My site’s grade was F on GT Metrix before downloading the plugin and it got to D and then I did the database cache, it got back to F so I unchecked it but after completing the settings, it stayed as F
3. Lastly, I wasn’t able to use the Elementor page builder while the plugin when the plugin was activated, but when I deactivated W3 Total Cache, Elementor started working.
