I changed the setting, but it does not get reflected in the pictures.

The setting you choose at 'change the settings for shooting' on the OLYMPUS AIR tag will be reflected to the camera when it receives input from other tags.

The settings is NOT reflected at the time when you press 'OK' on 'change the settings for shooting'.

Once the settings are applied by 'Change the settings for shooting', it will not be changed till you 'Change the settings for shooting' again on the MESH App.
