In cases where the user started to create a survey, passed the first page and than abandoned the survey, the system saved the name of the survey as ‘Temp’ in the DB.
Then, when trying to create a survey with the same name, this error appears.
We keep the name saved for 30 days and then it is removed, so the best practice here is to use a slightly different name and once the original name is free, they can change the survey name.
