I agree that it is not the most intuitive to have some of those sections in the "Account" area, however, if one were to put them somewhere else, it would require a new button to be created, which clutters the UI. There is always a balancing act between doing what makes the most sense, vs. doing what works best for the user in practice.
IMO, there will be a lower number of touches to find things (if the UI is not intuitive). What I mean is:
- Replace the account tab with the "Settings" tab.
- Settings tab would have:
- Account settings
- App settings
