why is my App Store and Safari not working on my IPhone 7 Plus

Try this next:

1. Launch Settings app on your iOS device.
2. Now, tap on Screen Time.
3. Now Content & Privacy Restriction.
4. Next, you have to enter your Restrictions passcode.
5. Now tap on iTunes & App Store Purchases.
6. Click on Installing Apps.
7. Now, make sure the switch next to Installing Apps is ON. If in case, it's Off turn it On.

Sorry I didn't think of it earlier.

What country do you live? Using a VPN?

Use Siri to open the App Store.

What error message do you get when you try to download apps?

Are you clicking on a link?

There was an error in the link (probably a typo) making it useless.

Ask Siri to open the App Store. You should not be able to delete it.

OK.

In your previous message from Safari there is a link (far right) to open the App Store. Click it.

Since the App Store can't be deleted yet you can't find or use it, you may need to restore your device using a computer.
