YouTube doesn't appear in my purchases (App Store)

Hey there MissThun,

Check and see if the app is hidden in your purchase history: Hide purchases from the App Store - Apple Support

What happens when you hide an app in your purchase list

When you hide an app in your purchase list, it no longer appears in the list of your purchases that's in the App Store.

"Unhide apps on your iPhone, iPad, or iPod touch

If you deleted an app from your iPhone, iPad, or iPod touch, the app doesn't automatically reappear on your Home Screen when you unhide it. Instead, redownload the app from the App Store. You don't have to buy the app again.

1. Open the App Store app.
2. Tap the account button , or your photo or initials, at the top of the screen.
3. Tap your name or Apple ID. You might be asked to sign in with your Apple ID.
4. Scroll down and tap Hidden Purchases.
5. Find the app that you want, then tap Unhide.
6. To return to the App Store, tap Account Settings, then tap Done.
7. Search for the app, then tap the download button ."

If you do not see these apps, do you have another Apple ID that you used on this iPhone? We ask because it is possible these apps were downloaded using that Apple ID. If that is the case, you can redownload these apps on your new Apple ID.

Keep us posted.

Have a great day!
