Where is mobile preview in AppSheet?
The preview in the editor sidebar shows what the latest version of your app will look like on a phone oriented vertically.
How do I add installs to AppSheet?
If AppSheet is already installed, tapping Install will open the app you shared (Driver Dispatch in this example) and create a shortcut to your app on the user's home screen. Tapping Go will open the Play Store, where the user can install AppSheet.
