I've created a survey in Survery123 Connect, but I'm not being allowed to publish it. At first I was getting errors when trying to validate my data. It didn't like that I had fields other than a "Date" field that were required. When I removed them and tried to verify again it now tells me that "Data values are valid Instance name: record_date:8/19/2019 12:00 AM". Even though it seems to tell me things are valid, nothing happens when I hit the publish button.
Are you signed in when trying to publish? And are you using AGO or Portal? Also what version of Connect are you using?
What is the error message you get when trying to publish, or does nothing happen? Are you able to share the xlsx file that gets the error?
