How to square off a BO position on Mobile Zerodha IOS app?

I have lost almost 20k in 2 days as i was not able to sqaure off the position on time from the mobile app. Our office has blocked all trading sites hence i have to use the mobile app? The IOS mobile app is good but there is a lot scope of improvement, not sure if any update is on its way. Any help or any suggestion on this is really helpful.
