Unfortunately, there’s no one answer for this direct issue. But in an email that we received from DoorDash support, there are a few things you can do to try and fix it.
For one, log out of your account and force close the app. Once you start it up again, log back in and see if that helps.
Even completely deleting the app and reinstalling it could help.
