Pianoteq + iPad + focusrite - one switch ON OFF

I play on pianoteq 8 with an iPad air connected with a usb-c hub to power supply, a Roland keyboard, a triple pedal and a focusrite interface. Everything works perfectly and perfectly silently, it is a perfect combinaison for me.
Several times inadvertently I interrupted the whole hub alimentation and connection before stopping the app on the iPad, it always reconnected immediatly without any problem, but my question is if anyone knows if there is any risk to the hardware (iPad or focusrite) to practice like this. I only use the iPad for pianoteq and it would be interesting for me to let pianoteq permanently open on the iPad. And only turn the main power on or off. Is it dangerous ?
Thank you for your advice
