@noywachtel Do you have any End of Survey block in the survey flow or any skip logic that direct you to that End of survey? You can start by checking on that elements.

yes as mention by @dxconnamnguyen there may be a skip logic/ branch logic on the block that you have applied which is taking the survey to the end . check the survey questions/blocks as well as the survey flow 

If the survey is working correctly when testing the survey in the preview tab, it might be because you have “ignore validation” turned on.

there is no logic or validation on the last question on the last block that was answered, I’m so sad cause I’m losing possible answers and can’t find the problem to fix it.

@noywachtel Can you maybe post a screenshot of the survey flow?

> Is there any skip logic in the first block that could be jumping people past the remaining questions and to the end of the block, where they encounter the branch?

> Is there a quota applied that could have been reached, and is now stopping users from moving through the survey?

 

Do you have any skip logic in the first block? Check Data & Analysis tab to see which question do the respondent stop at the 1st block. The problem might laying there.
