Q: I changed my Apple ID and now I can't update my apps

The only way to fix it is to delete them and then download again. Apps are locked to the Apple ID used to purchase/download them. Not sure exactly why you created a new Apple ID, but unless you use the old one, you will not be able to update those apps.

Your mistake was to create a new Apple ID, rather than changing the email address associated with your existing Apple ID. You will have to re-download all those apps, and pay for the ones that are not free again. Or go back to the old Apple ID account.

As far as the iTunes/App store is concerned, creating a new Apple ID is the same as a new account,  Purchases are not transferable from your old account to the new one and you'll have to repurchase the apps using the new Apple ID.

If you changed your email address, You didn't not need to create a new ID. You just needed to change the Apple ID, not create a new one. Apps and all iStore purchases are tied to th ID used to make the purchases. Creating a new ID means that you have to start all over again with your purchases. Changing the ID allows you to keep all of your purchases.

What to do after you change your Apple ID email address or password - Apple Support

Did you sign out of the old ID? Settings>iTunes & App Store>Apple ID. Tap the ID and sign out, then sign in with the new ID.

You need to sign out of the store, then sign in with the new Apple ID. To share apps set up Family Sharing: Family Sharing - Apple Support

• Go to Settings/iCloud and sign out
• Go to Settings/iTunes & App Stores and sign out
• Go to Settings/Facetime and sign out
• Go to Settings/Messages and turn off iMessage
• After signing out of all of these, go to each one and sign in with the new Apple ID.
• Delete any apps purchased or download with the old ID
• Go to the App Store and purchase or download any apps that you want
