I have developed a survey where one question has the following input mask - AA9990.
The survey is working as expected when using the URL or the QR code, and the user is prompted to input the answer to the question using the input mask.
However, once the survey is downloaded into the mobile app, the input mask is not having the desired effect, and the user can enter any data. I have created the survey in the browser version of Survey123.
Any ideas / solutions would be welcome!
