I have an iPhone 15 plus which I’ve just upgraded to from my iPhone 13 and the McDonald’s app stopped with error code 10051.
* I’ve managed to fix this by changing from my Mastercard payment method to Applepay (ironically using the same Mastercard 🤨🤨)
hope this helps people.
iPhone 15 Plus, iOS 17
More generally… Remove the app, remove any add-on VPN apps or add-on security apps, update your iPhone, restart your iPhone, re-install the app, and try again.
If that fails to resolve this, contact McDonalds support.
Based on postings around the ‘net, the McDonalds app seemingly works as reliably as their ice cream machines. 🙄
