Fixed Mobile app

Mobile app Help corrections

Help no longer says some mobile features are website-only when the app already has them.

The Help for the mobile app said that Store refunds and fulfillment, Message Board moderation and some Form building tools were only on the website. The app already has them: team administrators can cancel, refund and fulfil Store orders; board creators and team admins can remove any post or comment; and the Form editor supports every question and content type. The Help now says so.
