I wanted to book ticket on tatkal basis so i kept tatkal alert and it shows that tatkal booking will open at 10:30 am and tatkal alert notification will be sent 15 mins prior to scheduled time but to my disappointment no notification was sent and i kept the app open from 10:15 am and keep on trying to book ticket but it again and again showed opening time 10:30..but at exact 10:30, it showed a message sorry we seats book try another train...dont trust this app at all..
