I want to download Gacha life 2 but I have iOS 16.7.2 I need 16.1 what do I do

The requirement for the game is iOS 16.1 or later. iOS 16.7.2 is later than iOS 16.1, so it would appear to meet the requirement.

In any event, you can't downgrade iOS. If you're on 16.7.2 now, the system won't let you revert to 16.1.

Update to iOS 17.4.1, and try again.

Here is how to: Update your iPhone or iPad - Apple Support

And what to do: If your iPhone or iPad won't update - Apple Support

If you see a message that says your account has been disabled in the App Store and iTunes Store, contact Apple Support for help.
