Anyone else having issues with getting into the Sonic app….I deleted and reinstalled it, changed my password and everything
This has been happening to me for months. I tried deleting and reinstalling also. I tried resetting my password but the email never comes through. I’ve given up.
Tried the cheeseburger code on a Plain Sonic Cheeseburger through the app, and it says it’s not valid.
Sorry for the issues, Ellen. I just tested on a plain cheeseburger as well, and it looks like the code wasn’t accepted either; however, when entering it at checkout, there was a box at the top that showed the promo code then “Select Items” where you can add the qualifying burger to your cart. Hoping that helps! 🍔
