I set up free Trello account via browser yesterday on iMac and created a couple of personal boards. Today I loaded the Trello app on my iPhone and was playing. I closed a personal board (I am the admin and only user) without knowing what it meant and need to reopen it on the iPhone. Online help talks about displaying a board menu and then selecting closed boards and then selecting reopen, but I can't find such an option at all on my iPhone. Please advise how to reopen that board.
