After 1.0.3 the OIT is dead. Clicking the screen, which used to boot it, does nothing. Brightness is already at BRT, GPU and batteries are on, WASM is not crashing, and a full Marketplace reinstall changes nothing. The EFB just sits on "Awaiting Data / Initiated through OIS", so takeoff performance is gone. Your own FAQ still tells us to use an "OIS PWR" switch on the side console. That switch is not there. The actual power button is now hidden behind the oxygen mask box, by the yellow hose, behind the tiller, and it is off by default in cold and dark. Nobody documented this. People on this thread only found it by accident. I spent hours clearing WASM, reinstalling, and hunting for a button that your manual does not show. Shipping a paid aircraft update that silently kills the only performance calculator, then hiding the fix behind the oxygen mask, is a bad release. Put the computer back on by default, put the switch where the manual says it is, and stop making customers reverse-engineer a cockpit to get V-speeds.
