Can’t sign out of apple id

If you're having trouble signing out, here are some steps you can try:

Check for Restrictions: Make sure that you don't have any restrictions enabled on your device that might prevent you from signing out. Go to Settings > Screen Time > Content & Privacy Restrictions and ensure that you haven't restricted account changes.

Turn Off Find My iPhone: If you have Find My iPhone enabled, you'll need to turn it off before you can sign out. Go to Settings > [Your Name] > Find My > Find My iPhone and disable it.

Remove Device from Apple ID Account Online: You can also try signing out by using another device or a computer. Go to appleid.apple.com, sign in with your Apple ID, and under the "Devices" section, select the device you're trying to sign out from, then click "Remove from Account."

Check for App Store Subscriptions: Sometimes, active subscriptions tied to your Apple ID can prevent you from signing out. Go to Settings > [Your Name] > Subscriptions and make sure to cancel any active subscriptions.

Reset All Settings: If none of the above solutions work, you can try resetting all settings on your iPhone. This won't erase your data, but it will reset your settings to their defaults. Go to Settings > General > Reset > Reset All Settings.

Remember to back up your data before attempting any major changes to your device settings, just to be safe. If you're still having trouble, Apple Support should be able to provide you with the most accurate assistance tailored to your situation.

Is sign out or your account settings greyed out? This is most likely due to screen time restrictions, go to settings>screen time>content and privacy restrictions and turn those off
