Oh yes, that's bad... I saw also the same issue debated here:
That man have good videos... Anyway, I am a huge fan of Fujifilm for years now... I mostly record myself, so using remote app would be great option I thought... Big deal breaker. How is that even possible for such a great brand, 4K is not supported to shoot with app? Isn't it just like, why it isn't possible? Isn't it just like, just a remote thing to press start to start shooting, I can't see why it isn't possible... Maybe we can contact Fuji to update the app?
Also focus control inside app is problematic - there is no control at all.
For now, I switch to my smart TV as a monitor for shooting via HDMI cable.... Anyway, It is good, but it could be better to have the controls in front of me via app...
