Installing an App
You can switch the app you want to test by clicking on Select App on the left panel of the Device screen. When you click on Select App, a new screen with all your apps will appear. From here, you have two options:
You can click on the Add icon and install a new app version right here.
Alternatively, you can select any of the apps and versions you have uploaded before. Go to the app, click on the app version you want to install and click on the Install button.
