Managing Your Guild

How do you change the guild setting from "invite only" to allow any member to join, or change it so that only members with a certain fan base can join?
Open your guild building and select manage. On the left there should be an option that you can switch between invitation and open. Once you select open there will be a slider where you can set the amount of fans that your minimun requirement is.
I am playing on an iPhone 5s. When I select the manage option in the guild it only lets me edit the team name, description, and the status of teach member in the guild. I do not see the option to change the setting of the guild to open
Should be there. Would look like two buttons, one that says Open and one that says Invitation. Just tap Open.
Strange. It just isn't there on the manage screen.
I've even tried reinstalling the app
I'm having the same issue.
