new settings are not visible after downloading new version for couple of days

Why the settings are not visible after updating the application?

Even changes to the labels are not updated immediately - I had to wait 2 days to new settings.

Settings are handled online (device's settings is available from 3.2.0 cost code/memory).

- new app + new settings

- upload to store

- accepting new vesrion for downloading  - FROM THIS MOMENT NEW SETTINGS SHOULD BE READY

- users can download new app

- for couple of days users cant' use new settings or they see old labels...

It means users have to use default values hardcoded (if developer doesn't forget to handle it and it's additional waste of time/memory because default values should be always returned as defined in properties.xml but they don't or rather they are after couple of days).
