In this video I demonstrate three different ways to change the Owner for a PowerApps app.
1. Don’t actually change the owner, clone the app and assign a new Owner. Export the package, then log on with the intended Owner account and import the package. When importing, select Create New for the app.
2. Use the Share functionality to make another user a Co-owner.
3. Use PowerShell to CHANGE the app owner. Previous Owner becomes a User. Previous Users remain Users.
