Auto lock after auto open door

Hi everybody,
I’m experiencing some weird behavior with my Nuki 2.0, one of my users suddenly have this: when he is getting near the door the door is opened and this is great, but immediately the door is locking, can’t find the reason for this and it happen only to 1 specific user (Android phone), do you know how to solve it ? make me crazy :frowning:

What’s in the activity log of the Smart Lock?
