Would definitely not wait to the day of travel.
But there is no indication that the ticket has been cancelled. A flight being rescheduled or being cancelled does not lead to the ticket getting cancelled (that would be very unfortunate in respect to the remaining segments (HK; confirmed) in the ticket). The ticket is still there but the check-in staff will see that the OP is no longer confirmed for the 1 of flights and will have to deal with it (or most likely ask the OP to go to the ticket counter) to get to OP to the ultimate destination. I agree that it is a last resort (and many will not be able to deal with the uncertainty and stress associated with being on an unconfirmed flight and knowing that you need to get rebooked at airport), but if the OTA refuses to clear up the mess, the OP will have to proceed like this.
