Hi John,
When you say web browser, do you mean the web app, are you trying to view the survey form to collect new survey? Or are you trying to view data on the survey123 website via Data tab? Where does the error ocurr you sent above?
Can you send a copy of the xlsx form and any csv of data in media folder you created from Connect? It sounds as if something is missing or wring in one of the expression, csv or choice lists?
We had a website and web app update to 3.3 a few days ago, please make sure you clear you cache of your browser and try again, this could resolve the issue.
Phil.
