Unable to install App Store on iPhone

For starters, you cannot delete the App Store, so it must be somewhere.

• Go to Settings > Screen Time > Content and Privacy Restrictions > iTunes & App Store Purchases > Installing Apps and make it set to allow.

• Swipe all the way to the left on your iPhone and search for the App Store in your App Library.

Also please take a look at the following article ⇢
