might not be able to mix with a meal, they cant redeem both vouchers at the same time. last few times they had to do a specific redeem for each coffee.
honestly if they just left as a gift card would have been a ton easier. i will say that it has been a bit easier with tellers over last week as i say cashback.
if not mistaken you need to specifically tell them to swipe your loyalty card then can swipe your credit card. if you dont do a loyalty swipe wont apply.
i see there was changes to app section. assuming needs a few more days till vouchers are back and all new features live.
i see they added goals and a minimum of like 20 vouchers etc.
