iPhone won't let me choose the passcode I want
I want to change my passcode but when I put in the one I want to use I get a message saying that the passcode is easily guessed and it won't let me use it. The passcode is not easy in my opinion and I have the same passcode on my iPad and Apple Watch. I want to have the same passcode for all my devices. Why won't my iPhone allow me to use the passcode I want? I am up to date on firmware and I tried to do a restore from a back up and I'm still having this problem.
iPhone 11
