Completely uninstall Grammarly and whatever else is associated.

I tried out the grammarly app, uninstalled and removed the safari extension. Unfortunately, its underlined blue colored spelling and grammar corrections continue on, making my daily works, and writing tasks unnecessarily more difficult. I have tried other apps to uninstall, but whatever is remaining is causing these continued problems.

I desire the pre-Grammarly install performance.

Any other suggestions are appreciated.

Thanks...
