Until now, the Google Ads app hasn’t supported manager accounts, which was pretty strange. Until recently, when you sign into the app, you’ll see any manager accounts at the top level.
Support for manager accounts was added to the Microsoft Ads mobile app a few updates ago.
The increasingly present optimization score can now be seen on the main manager account dashboard in the Google Ads app. Optimization score was just added to all account Overview pages in the web UI and app recently as well.
