Mc Donalds App redeeming errors

Has anyone else had a problem with the mc donalds app when trying to redeem deals or the point that you have earned? This seems to be an ongoing issue. Its happened to me and to other people i know. You earn points and when you try to use those points to redeem something it says "content not available". It then appears after a few days again and the same thing happens. This is so embarrassing and then you end up paying cash for it. Totally misleading and deceiving.
