Thank you for taking the time to provide feedback, and I apologize for the unsatisfactory results you experienced.
Regarding your website not getting a high score when investigated by external tools, it may not be the plugin’s fault but depending on the time of testing and the load status of the server at the time of testing.
Each website has different characteristics, as well as installing different plugins is one of the factors that affect the performance of the website.
Can you give me more information to help you try to debug the problem?`
