Why would a manufacturer do that? Seems like they just want to make the lock difficult to work with!
You might consider looking into if there is a different mortise lock you can get for the door that doesn’t require all the extra movement to lock and unlock.
I ended up getting one. Klug k1. Will report back if it works. But either way I had to pull handle up to mutlti point lock. But it does have auto latch lock. Not as secure tho
Hi - did you end up finding a smart lock that works for this configuration? I have a Pella door that has an identical locking mechanism to this (with the vertical deadbolt) and I’m beating my head against the wall trying to find something. I HATE this existing door lock with the finicky “pull up to lock or unlock the deadbolt”
