IOS app - lock remote option

Hi,

I think we have issue with iphone iOS user(s). When they disconnect RDP session is being locked. Our preference is not to lock on disconnect.

I am used to Windows app, Options>Advanced>Lock remote computer, can set to "Never"

I am not (un)lucky enough to have an iPhone. Can some one tell me if such an option exists in iOS app or if no option then what is default lock behaviour?

Any info appreciated.

Thanks in advance,

Michael
