Scheduled Lock and Unlock

I had setup scheduled locking at 22.00 and unlocking at 07:30 next morning for every day in the week .
Locking works perfectly - unlocking not !
Do I have to have Nuki app active all night long ?

… sorry about that (stupid) question. My fault.
Didn’t realize that I have to set 2 timers / one for lock and the other for unlock.
