I notice that when I use a button to navigate to a separate screen (I’ve tried using bottom bar navigator wit the same results), and use this code: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/b/4b11515da8ffa2a4347e1c61b814ef0f1e578603.png) The scanner wont be brought up, I think it’s a bug because before this it could work. Any help? ---

try it easier - run through the button! this should work. Perhaps you don’t have permission to use your camera? ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/5/151228032b6c396378b26944a0b2d630da36ac0a.png) ---
