3. Check the device date settings

On iOS and macOS, the proper functioning of some apps and features depends on the correctness of the “Date and time” configuration of your device. For example, you might not be able to install an app from the App Store if the date and time on your iPhone, iPad, or MacBook is incorrect. It could also disrupt the synchronization of calls and messages between your Apple ID devices.

Make sure your iPhone / iPad and MacBook are set to automatically update their “Date and Time” settings. You should also make sure that they are both set to the correct time zone and location. Here’s how to do it.

Check date and time on iPhone / iPad

Step 1: Launch the iPhone settings menu and tap General.
