How to relink an AdMob app with App Store app

Motivation: You have an AdMob application that already links to an incorrect Google Play app or Apple Store application. You want to change this incorrect link.

Solution: If the app is already linked, you can’t change it. For Android apps, you can add additional stores after linking.

The only thing that you can do at this moment is to go to Apps > VIEW ALL APPS, then find the correct app you linked, and create a new ad unit for use.

How to change Apple Store seller name?

Motivation: You have an Apple developer account used to publish your applications to Apple Store Connect. However you do not want your personal name to appear as applications’ seller name. You want to change your personal name to an alias, nickname, or company name.

Solution: The only way to change your personal name to an alias, nickname, or company name is to convert your Individual developer account to an Organization developer account.

In order to do it you have to prepare the following information:

1. A legal entity (i.e. a legal organization or company).

2. A D‑U‑N‑S number.

3. A legal binding authority (i.e. a legal approval from organization’s owner/founder).

4. A website

Then you need to contact Apple Developer Support so that Apple can make the change for you.
