Access from app is not registered in user profile as course access

We've the situation that the users activity in app is not registered as last login in user profile.  A user was logged in the last time via browser three month ago. This date is visible as last login.  The same user made a feedback activities two weeks ago that was registered via web services.

Is it correct that the last login date only includes web browser access but not app access?

I think this should be improved. If more and more users uses the app the last access date should include app activity dates also.
