I have a project that I successfully build for Ad-Hoc iOS with my own google account, using the account of my partner, it fails:
What should I do to be able to compile uisng another account. (Works on both account when building for Android)
My iOS account is not a google account and runs well. Keep attention with the iOS profile AdHoc file for every user. It will be well attached on the App.
Did you follow these steps?

Each App Inventor account has its own keystore, so if you are using two different App Inventor accounts you will need to generate two different certificates and ad hoc profiles in the Apple Developer Portal. Alternatively, you could load a copy of your keystore into your partner's account.
