Why is Delta Exchange India not updating it chart api for better trading experience?

Hey, i have been using the Delta Exchange India for a year now and it hasn’t updated since its inception. The product Announcement page is already closed. Aren’t there gonna be any update relating to Chart API? Plus, it isn’t the case that the current chart api is functioning perfectly without any problem, i can list some issue the price and candle don’t sync in the live trade in the Chart API, Moreover, from the mobile app the Stoploss and triggers can’t be adjusted in the first go from the chart, that’s a big headache. What the fcuk are developers doing for upgrading the system or company has already thought of sitting only on the profits. Soon there’s gonna be a second app with better tech and less trading fees than you guys, which is gonna hurt you later.
