Uninstalling and reinstalling an app
I deleted an app from my phone so that I could re-install it as it was not working properly. I keep getting an error when I try to sign in that says "Invalid user ID or password", Even though it is deleted from my screen it still shows installed when I go to apps and it will open when I push the open button. I need to know how to completely uninstall and then re-install in order to make this app work properly. I have followed other answers, yet none of these work for me. Can anyone help me? This an iPhone SE 2020.
iPhone SE, iOS 14
