I have a few participants that say they are not receiving surveys for the study #962:
#27441 is registered to the study but indicated that they have not received any surveys yet, I have also tried sending them the surveys manually, however they also do not receive these surveys.
#33724 had a lot of problems registering to the study, and did not receive the eligibility questionnaire even when I tried to send this survey to them manually
#31625 was receiving surveys for a few days and indicated to continue receiving surveys, but from 26 to 30 November when they opened the app there was no survey. It seems like they could answer the survey from yesterday, but we would like to prevent the problem from happening again.
I was wondering if there was an underlying problem that causes this and if we can prevent this from happening with other participants?
