Usually (I’d say 99.999999% of the time) when the app doesn’t see the local console it is because the mobile device and the console are not on the same network. Perhaps the phone is using a cellular connection and wifi is turned off, or the phone’s wifi was wonky and a reboot fixed it.
As far as the slider on the right side, that is obviously a “resizing issue” with the app. The app is suppose to resize itself automatically because every device is going to have a different screen resolution and the app should work with all of them. You should submit a formal support ticket (from the main A&H website). This forum is not “official support” although the A&H team certainly monitors the posts here. Hopefully A&H can fix this, but you might try changing the screen resolution if it really bothers you.
