Received the debit card and chequebook today. They did create a joint account, however issued only one debit card even though I had requested for two cards. Will visit the branch to apply for the add-on card. As per the tnc booklet, the add-on card will also have 0 issuance fee and 0 annual fee (subject to transaction criteria).
Please note that you will need CIF no of both the applicants to log into the app for joint accounts. I am not able to log into the app using account no. Will have to visit the branch to get passbook which will have the CIF details.
