Mobile app can not download on Google Play

Go to the App Store, or Google Play and download the Xbox app. You can then upload your game captures to Xbox Live, then use the mobile Xbox App to download your captures after they're uploaded to Xbox Live. You can also click on the share options for
your captures and upload them to Onedrive and use the mobile Onedrive App to download to your phone.

All we need to do is look at what happened with google:

"Google Inc. has agreed to settle a Federal Trade Commission complaint alleging that it unfairly billed consumers for millions of dollars in unauthorized charges incurred by children using mobile apps downloaded from the Google Play app store for use on
Android mobile devices. Under the terms of the settlement, Google will provide full refunds – with a minimum payment of $19 million – to consumers who were charged for kids’ purchases without authorization of the account holder."

You can but only thru a third party device or a mobile device for alexa or google now

If it's android mobile, then find the app in the google play store, and select uninstall. It will not revert to the old app though. It will just remove it altogether.
