Stopped in local McDonald's this morning and asked for my normal free small coffee and they asked me to show the coupon in the app. so no coupon to scan eqauls no coffee.I am using an iPhone and nowhere in the app is the coupon to scan. They said a lot of drivers are very upset about this but to me not a big deal for a $1 drink. I logged into Uber via the web and it shows the McDonald's promo and what it looks like. Perhaps it is only in the Android app.
