IPhone won't let me accept new iCloud terms and conditions

I have an iPhone SE, iOS version 17.7.1. I have this notice in Settings: "To use iCloud on this iPhone you must accept the new iCloud Terms and Conditions, and enter your iPhone passcode." Right below this is "Continue" in blue. I hit "Continue" and the screen shrinks for a moment like it's about to be replaced with another screen (which presumably would allow me to review and accept the new T&C), but it never actually goes anywhere; it remains on the same screen with the same quoted language, and the same "continue". I've tried signing out of my Apple account and signing back in again but it made no difference.
