Consistent nonexistent promo code issues – Grubhub: Food Delivery Review

I have consistently had a problem where I haven’t applied a promo code but it says my promo code can’t be applied and that I should remove it. I DIDN’T EVEN USE ONE. It won’t put my order in until I remove the nonexistent promo code. This happens every now and then and lasts for a few days. I’ve started using Doordash instead because I literally can’t order food on grubhub.
