Zone leave automation does not trigger

Hi,

I have my home zone and I’ve created a “house surroundings” zone with my house at the centre and a radius of 450. So that this zone doesn’t appear in the user status, I’ve indicated that it’s “passive”.

I’ve created two automations: one for when my wife leaves the zone and one for when she enters the zone.
However, I have a problem: every time she enters the zone, I receive a notification, but most of the time when she leaves the zone I never receive anything, because the automation is not triggered (it worked one or two times). Here it is:

trigger:
  - platform: zone
    entity_id: person.wife
    zone: zone.home_surroundings
    event: leave
action:
  - service: notify.mobile_app_fold_5
    data:
      message: Test
mode: single

She have the Android companion app and the location seems to work well.

Any idea ?
