Hi- I am having a very similar issue .
I have two surveys linked to the same hosted feature. One is for the field staff to collect information and the other is for a committee to review the information from within a Dashboard.
I am using s123 Connect 3.13.239.
I have a dateTime field with the default field set to now() .
Should also note that I tried today() in the default field, as well as change the field type to date instead of dateTime.
In both the s123 Connect preview and when I launch the survey independently in browser, the Date of Review value is populated as expected.
But, when I put this survey into my Dashboard (where review staff will be able to see and jump around from issue to issue to review, the Date of Review field it is empty:
Testing out a few things, when I did add the now() to the calculate field it gets me a bit closer to auto filling the value, but I still have to hit the "reload" button to get the date to populate as expected.
