Wrong Email in App Store Pop-Up

Hey there AndrewMora,

We'd like to help! To address your first question, there's no 'App Presences' setting option from the main Settings screen on your iPhone. For your second question regarding seeing your older Yahoo account when being prompted to confirm purchases, there's several reasons why this could be occurring, so we'd like to narrow them down some. We also want to rule out some basics:

1. You mentioned that you used an old Yahoo email account as your Apple ID in the past, but are you still using the same Apple ID account currently and only changed the email account associated with it? If you used an entirely different Apple ID account, then what you're seeing is expected as it would seem that you made some purchases for content using an older Apple ID account. It's always recommended to change the email associated to your Apple ID if needed, instead of having two different Apple ID accounts, which could cause this kind of issue to occur.
2. If you check your currently signed in Apple ID associated email accounts, is the Yahoo one still showing? This article has more details about checking this under the section 'Additional email addresses' here: About your Apple ID email addresses
3. When does the prompt you're seeing show on your iPhone, and when did it start to first show?

Cheers!
