I really don’t know.  It may be different if done from a mobile device or through the tech portals with wi-fi connection… @Björn Kleist , do you know?

Hi @Djedai ,

In Mwo App support offline mode and you don’t need network connection during answering the survey .

But if the app close accidentally or device off due to battery dead then there is a problem.  

mwo survey answers save at the end. So effectively you need to start from beginning.

Even though not directly help here, we have ‘Temp Save’ in survey config. So suspend button will appear. There you can save answers in the middle. But again it not automatically save answers while you entering. 

Thanks Bandula!

Thanks @Bandula 

Best regards
