I have a Public Notification Instant App set up with expressions in the pop up to eliminate "null" values in the owner field and to make the municipality all uppercase. Last week the labels were exporting out into a PDF format with no issues. Yesterday, when I was testing, the exported PDFs and CSVs now show {expression/etc} instead of the values. I am not sure what happened here. I tried to redo the expressions, but I am getting the same results.
Expressions(2 separate) used:
var owner= $feature.OWNERNAME1;
IIf(IsEmpty(owner), 'Current Resident', owner)
Upper($feature.MUNINAME)
Popup and set up in web map (works as expected):

Output from Instant app:

Any thoughts on this??
Thanks, Mary
