Did you get an pop-up window stating you need to update Armed heist?
Our latest updates will always be available in the official App store or Google Play Store.
(Please note that the availability in the store may vary some times after we've recently done an update)
We recommend all of our players to check their platforms store (App store or Google Play Store) in order to make sure they are running the latest version of Armed Heist.
If the game is not updated to the latest version, then you may experience issues with the app not starting.
