DuckDuckGo removal
Every suggestion that I can find to remove DuckDuckGo from my iphone 13Pro says to go to Safari>Preferences. But when I go to Safari, there is no 'Preferences' choice whatsoever. Other sugestions say to tap DuckDuckGo icon, but there is no DuckDuckGo icon, and using the search function brings up nothing. I am having problems with DuckDuckGo blocking my outgoing mail. Help?
