I was able to use the McDonald's app until November 14, 2025 in the USA. The app was updated and has had various issues. The first issue after November 14, 2025 was the App would work to make purchases and for points. Rewards stopped working.
A few days later, after I had reached out to McDonalds, the app started claiming that it wasn't near McDonalds to get a code. After holding up lines multiple times, I've decided to go elsewhere.
So far Burger King works.
