Error in uploading participant's results - Data loss

What link do you use to run the experiment?

Sure, here is the link

@apitiot I know this was a long time ago, but could you please confirm whether data loss can be caused by many people completing an experiment at the same time? We are about to start in-school testing where we will have groups of children completing the same task at the same time on individual tablets. Can we be confident our data will be properly saved? I’d appreciate a quick response if possible!
Best wishes,
Donna
