Voting runs as expected and the results preview shows data but when you export to Excel you get this error at the point of confirming the file name for the Excel.
This can be caused by a special character confusing the export process. To generate the error, we used a colon symbol in one of the answers.
Check your slides and remove any colons that are present and try again. If there are no colons, look out for any other punctuation that may be confusing the system. Feel free to reach out to our team if you cannot identify what is causing the error to appear. We will need you to send us a copy of your presentation to look through.
