How to fix App Store disappeared from iPhone?
1. Check your restrictions. If you have enabled restrictions on your iPhone, then you may not be able to access the App Store. To check, go to the Settings app and then select ‘Screen Time’. Select ‘Content & Privacy Restrictions’ and make sure that the ‘iTunes & App Store Purchases’ toggle is set to ‘Allow’.
2. Sign out of your Apple ID and sign back in. Go to the Settings app, select ‘iTunes & App Store’, select your Apple ID and then select ‘Sign Out’. Once you’re signed out, sign back in using your Apple ID and password.
3. Make sure that the App Store app is enabled for your Apple ID. If the App Store remains missing after signing out and signing back in, then check if the App Store app is enabled for your Apple ID. Go to Settings > iTunes & App Stores and make sure that the ‘Use This Apple ID for App Store’ toggle is turned on.
4. Restart your iPhone. If the App Store still isn’t appearing, then restart your iPhone to see if it resolves the issue.
5. Reset your iPhone. If restarting doesn’t help, then you can reset your iPhone by going to Settings > General > Reset > Erase All Content and Settings. This will reset your iPhone to its factory settings and will install the latest version of the operating system. Make sure to back up your iPhone before resetting it.
