In the investment section on mobile (iOS) you can adjust the sorting order for your holdings (in the holding tab) or accounts (in the balances tab), but theses preference are not saved.
When you log out and then re-log in, they tables revert to being sorted according to default settings. Same goes for the toggle/preference to show 1-day bs 1-month change,etc.
It would be great and seem like good ui to let these setting be saved/preserved from session to session.
