The "auto launch" setting in VMcast helps your app restart automatically — handy if the power goes out, or if you're managing multiple streams or locations.
Install the VMcast app on your Amazon Fire TV Stick.
Once the app is launched and you're logged in, look for the "Settings" option at the bottom of the VMcast menu screen. If a loop is playing, you may need to press the "Back" button on your Fire TV Stick remote.
Select "Settings".
Scroll down and select "Auto Launch". The option will change from "Off" to "On".
Your device is now set up to automatically launch the VMcast app.
