Grammarly - Unwanted

[BuggeredCustomer]

How do I remove/disable it permanently? 

According to the Settings within my phone it is not active. Yet it most definitely is. STILL. 

I don't want it.

I never installed it. 

I have no use for it.

I have better use of my space on my phone than apps I don't use, of which this is one.

Hi, Open the keyboard and tap the settings icon in the toolbar or navigate to it through the system settings menu.

1. Navigate to Settings > General management > Samsung Keyboard settings.
2. Scroll down and tap the Select third-party content to use.
3. Disable the Grammarly keyboard integration from the menu that opens.

If you find that Grammarly doesn't remain disabled, try clearing the app cache and restarting your phone to see if that helps.
