Recently, my Apple phone can't automatically enter the SMS verification code (even if "Settings-Password-Automatically Enter Password" is turned on)?

Apple mobile phone can't automatically enter SMS verification code. SMS verification code and password are two different things. See Settings-Password-Auto-Fill (not Auto-Input). This step is wrong. This function is that the password system generated in the process of using the app will recognize and automatically fill in the specified function. Mobile phone verification code is a set of numbers assigned to users by SMS during the registration or login process of Apple mobile phone using app, and filled in the designated place. Apple's mobile phone doesn't seem to have the function of automatically inputting SMS verification code, so it needs to be manually clicked and then automatically input. Not all SMS verification codes can be clicked and entered, which is related to the programming of software developers.
