When configuring the Hint field in Survey123 Connect for ArcGIS, I noticed that it will not accept <, but it will accept >. I had an issue in previous versions where the % was causing issues, but this time any text after a < does not show up.
< might be a reserved character in HTML. Have you tried using < or < instead? - more help here: HTML Entities
Neither of those return the results I am looking for.
I've just given it a quick go and < has worked for me:
I'm on Survey 123 Connect v2.4.60.
Are you able to share your spreadsheet?
