Updating the VMcast app on a Fire TV Stick
The Fire TV Stick will update the app automatically given enough time. Here's how to update it immediately.
Go to your TV. Make sure the Fire TV Stick is the active source displayed on the TV.
Press and hold the home button on the Fire TV Stick remote for a few seconds. A quick access menu should appear covering the entire screen.
Focus the VMcast app tile, but do not select it.
Press the options button on the Fire TV Stick remote. A context menu should appear in the bottom right.
Select “More Info.” This should take you to the VMcast app landing page on the app store.
If an update is available, the button below the description should say “Update.”
Once updated, the VMcast app version should show as 3.0.9 or greater.
