App freezes when participants try to submit responses


We have the following problem with out study (ID 1413): Two participants (EID’s 37717 and 37705) report that their app freezes when they try to submit responses. I am not sure whether this lead to missed responses as they do not know exactly when it happened. What causes this?

Kind regards,


We do receive reports every time the app crashes and my colleagues investigate these errors and fix them.

For the two cases you mentioned, they have completed all surveys as of now, so I doubt if this is really impacting their participation.

Thanks for reporting it.
