Hi,

participant #14123 in study 835 fills in a survey once per day. Between 29 december and 8 january I can find no record of this participant’s data, although she did complete the surveys in that period. We tried synchronizing her study with the blue button in settings, however the data does not appear. In this period, it also does _not_ say that she did _not_ complete them (e.g. ‘expired’), which is curious right? Is there a way that we, or you, can retrieve these data that appear to be missing?

Kind regards,  
Nicky Schippers

Hi @lgosens ,

Those sessions are updated now. In your case all those sessions are expired, the reason is participant has switched between two devices and those pending sessions are the ones supposed to be handle by the old device which is not used anymore.

Thanks,
