After completing some items in the survey, the same page reloads when I click on "Next Section".

The survey has been successfully tested end-to-end in many places round the world.  However, we recognize that there may still be issues that need correcting.  We run continuous checks to ensure that the system is operating as required and will continue to do so.

However, the problem may be due to a local issue on a respondent’s computer e.g. the use of a specific browser. Please try answering the survey using a different browser.
