Update Apple ID needed

Read the document:

Manage Apple ID settings on iPhone - Apple Support

- Make sure you are signed into your account. You said you weren't signed in and this might have prevented your device from doing something and hence the "update" message.

- Verify payment method(s) and billing address as described in Add a payment method to your Apple ID - Apple Support . Items in red have problems.

- If you're using other Apple IDs with services such as Messages or the App Store, make sure those are signed in too.

Other things to try:

- Check that there isn't an issue with Apple's servers: Apple - Support - System Status

- Try restarting your device.

- Check your software is up to date.

If you still have questions or problems:

To contact Apple, click here --> Choose your country or region - Official Apple Support

Select your country, then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.

or:

Contact Apple for support and service by telephone --> Contact Apple for support and service - Apple Support

Hey there cpwciii,

We'd like to help by first ruling out some possible causes, along with confirming more details to better understand what's happening:

1. When did this start to occur?
2. Where exactly are you seeing this message within your iPhone?
3. Sometimes unexpected behavior can be resolved with a restart: Restart your iPhone
4. We see that you have iOS 16 installed, but the latest version is iOS 16.3.1. You can verify this within Settings > General > About. In case you needed it, this link shows how to first back up, then Update your iPhone or iPad.

Cheers!
