About this bug, my survey doesn't have Read-only = Yes on selections question, BUT It has several Hidden question whit Read-only=Yes, It's possible another bug?
A few different things that I have noticed.
Comentarios de Ing Sitio, isn't editable even in the Survey123 Connect application. When I go into the browser I click OK to the error message and then am not able to edit only Comentarios. I did a quick test and removed all Commentarios de Ing Sitio and this was successful without producing any errors in the browser.
At first, I thought it could be multiline predictivetext that is causing the issue but Observaciones is still in the form without causing any errors. Is there anything else in particular to Commentarios de Ing Sitio ?
