One of our enumerators is experiencing having a 'Sending failed' completed forms

One of our enumerators is experiencing having a ‘Sending failed’ completed forms. They are in the Sent tab already so they can’t edit it or resend it because there is no option. Anyone who may have a workaround for this?

Welcome to the community, @data_wrnumero! Could you also share a screenshot of your app’s home screen with the community so we could see if there are any submissions under the Ready to send tab?
