First of all, only the person who has created the survey is able to evaluate it. 
 
First, open the survey that you want to evaluate.

1. News

Click on the three dots in the top right corner of the news that you want to evaluate and select the "Survey evaluation" option.

You will now see an overview of how many people have already voted and how many have not. Here, you also have the option of exporting the survey results as a list.

2. Chat

Click on the three dots in the upper right corner of the chat message that contains your survey and then select "Survey evaluation".

Please note: only surveys that are not anonymous can be evaluated. In the case of anonymous surveys, you will only see a percentage of the results and the number of votes cast per answer.
