In my survey there is a question asking people to provide an email address, and I have set the constrint field to verify that there is an @ and domain, etc...
https://survey123.arcgis.com/share/12d553750d514467ac83b9fdc63181c1
but the phrase "dies ist eine ungultige Antwort" (this is an invalid answer) is below the field before the people fill in, and even after when an email is entereed correct. try it and you will see.
bizarre? There is nothing in my form but the constraint: regex(.,'^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$')
How can I stop my survey from scaring people away with the invalid answer statement?
