In order to ensure that participants only use a compatible device when taking your study, you first need to make sure that you have clearly specified what devices are compatible in your study description and also indicated this by using the options on the study set up screen. Please see here for more information.
If you have included these requirements in both your study set up and your study description, submissions from incompatible devices will not require approval. We recommend that you contact the relevant participant(s) and ask them to return their submission. If you do not hear back from the participant(s) within 5 days, please contact our Support Team using the button below.
