Is anyone else having a problem to receive OTP for online purchase with YOLO card? I have tried to make a few transactions from different merchants (TM Portal, Maxis) and the OTP never comes.

UOB Customer service is no help, they just keep telling me that  my card is fine, phone number already registered, ask to restart phone, restart PC, etc.. 

luckily not finished, yet.

almost waited for midnight to buy, too tired, just try this morning 

since limited to YOLO, may not finish that fast.
