Hi @erania-pinnera,
Thanks for taking time and responding to my query. I can access the report (I was talking about the screenshot and Speed Visualization on Report itself.
For your reference, Here is the screenshot – https://gtmetrix.com/reports/dotnet.guide/jwwDwMDM/screenshot.jpg
I have disabled and enabled Plugin again and regenerated CSS. This time it worked in single click as I didn’t navigate away from browser tab.
Also, I have customized post style and its showing fine now. Website is faster then earlier.
Thanks for such outstanding work.
