I created a one-day pilot version (study code 972) of my study to allow coworkers to experience the ESM for themselves. However, after registering, I and others get an error message and do not get any questionnaires.
Looking at one of your participants history reports the error relates to a survey with notification offset beyond survey timeout period. It is survey id 5057, notification id 3 with offset: 60000000ms which is beyond survey timeout duration of 2700000ms. Please adjust that value.
Participant history is a great tool to investigate participants activities further info can be found here.
