Installed the App a while back, but since then have noticed some issues on the website score aswell as the search and page loading, some pages do not respond, and after doing some digging we found out that its the App.
have since removed it but the issue still persists apparently the app makes changes on the them and only the developer can help.

The app does what I need, but the app has a very negative impact on page load score. My webpage speed became unacceptably low immediately after installing. I still haven't found a replacement, though, so my site continues to get horrible speed rankings (and, yes, even google's developer tools point to this app as the cause of the slow loading). Fix that and this is easily 5 stars.
