The Dec 10, 2016, update fixed it

This update fixed it.

Old feedback: Bring back the previous app that worked. Used the previous version frequently, gave up and deleted this one. McD. Needs to replace the exec. that approved this mess with someone that understands customer experience! User error?? Must be using the previous version!
Since the latest update app will not work on MCDonalds wifi. Worked prior to the last update.
As of December 2016, gives ssl error if on McD wifi.
Works with wifi turned off.
Visited store on Harbison in Col. SC, today to use Mac Jr 2 for 1 coupon, they no longer sell them.
