Looks like Wendy's doesn't like it when you use the classic single for a dollar March Madness 2022 offer too many times. If I try to use it in the app now, the app crashes. All other orders and offers work fine. Clear data, cache, reboot phone, reinstall do nothing. And I can't submit it as an order from any web browser on any device, so I know it's tied to my account. One per day during the offer period. That's what they wrote. I guess that's not true. Dave would be ashamed.
