Like the title says, we have three GP tools that we have used for the past few years with no issues on other apps (built by a third-party consultant), but when trying to use them with ExB they will not work. I have added the utility as the organizational default and it does work at all custom sizes with New Map Viewer.
I have tried both adding the utility directly with the REST service link along with adding the item to AGOL and then attempting to add the utility to the print widget. The result with both is the PrintTask will be 'added' and the text "Click the “Select utility” button to add utilities for further configurations." returns right after.
Thanks!
