Voila! I finally figured out how to restore and use the McDonald’s app after several months of it not allowing me to log in from my iPhone 11. Here are the steps: 1) Settings 2) General 3) IPhone Storage 4) select the McDonald’s app 5) click Delete App 6) go to App Store 7) install McDonald’s app 8) sign in or reset your password. Mission Accomplished!!!

I havent been able to use the app since late July 2020. I updated it one day and the next it had the error. I have an Iphone X my partner has an XR and it works fine on his. I have literally tried everything and talked on the phone with McD and they said it was a known error and they think it was because of a different app on my phone that doesn’t correspond well with theirs. Thats and odd excuse but whatever. I doubt they will ever fix it and I am noticing a trend for it having an issue on “older” iphones models more than any others. Hmmmmm... if anyone can figure it out let me know...
