I changed my Apple ID and now I can't update my apps
I just created a new Apple ID and expected to lose all of my apps, but I can still use them. I already logged into everything with the new ID. The issue is that now I can't update them and the app store doesn't recognize them as purchased, but also won't allow me to repurchase them. When I click update, it prompts me for the password of the old ID and won't let me change it. They are basically in limbo. Any ideas about how to fix it? Thanks!
