Crap update nothing works

I opened up the McDonalds app to try to see what was the latest deal for tonights dinner. It wouldnt let me login. So I checked the Apple store to see if there was an update and saw there was. I updated to the latest one. Now it says there are no deals anywhere around me. Even though earlier this morning I got a notification saying free six piece chicken McNuggets with the SD Padres win. This app is useless now. Please fix it. You broke something that worked. Minor bug fixes my butt
