I installed this app to help me increase my website's speed, because I was unable to edit my code and remove the scripts myself. After this app helped me increase my speed 30-40 points, all of the sudden it stopped doing that.

Unable to reach anyone. App not working. The comparison page speed does not load at all. Tried emailing 3 times no response. Also if you have something like Pagefly, it will cause issues.

This app is AMAZING!! My website speed is so much better now according to Google PageSpeed Insights. Even on mobile it loads very fast (I used to be in the red zone all of the time, even with the use of other page speed booster apps). Now I only use this app and I'm very happy with the results. Thank you for doing such an amazing job!
