I just called and they mentioned that the credit card team would be available post 10 AM.
They have arranged call back, I would probably get access by 10 AM, if not, the credit card team would enable it from their side.
Now go to Passbook section of app and it will show a infocard saying "Reserve your FD backed Credit Card". You may need to scroll sideways if it shows others like "REPO RATE DROP" etc.
I called CC cust care and they said 5000 cards not issued yet so mine is LTF. Probably already issued but they are just giving LTF to attract a customer base for now.
