Remove Bing search engine from my iPhone 11

For Safari go to Settings->Safari->Search Engine and set it to whatever you want. You can't remove the Bing Option, but you can set a different search engine for Safari instead.

Go to Settings, Safari, and choose what search engine you want as a default from the provided list.

Do you have a work email account on your iPhone? If yes they may be limiting you to Bing. Also check restrictions under Screen Time.

And restrictions?

You might also try a forced restart: press and release the volume up button, press and release the volume down button, hold the side button until the Apple logo appears, let go of the button. Then try again.

First, check to see if bing is in the app list within settings. Go to the App store, check under apps you've purchased and if it's there, delete it. Otherwise go to what ever browser you use, go to their settings and change the default search engine to google.

If you use the MSN website, then it by default uses Bing, you cannot change the search engine the MSN wesbite uses. Its their website, and they get to decide what search engine is used when you use their search box.

If you want to use Google, open google.com instead or simply use the address bar at the top of Safari to search rather than the MSN search box.

What search icon?

Just type something in the address bar at the very top of the App, and then tap the blue go button on the onscreen keyboard.

So the question now is, how exactly do you initiate a search?

What are the steps you follow exactly?
