Recently I wanted to test out the time triggering logic in my study (Study ID: 1453) by signing myself up (with a personal email account) as a participant, but I can’t seem to sign up for my study. I get some kind of error saying I’m unable to register for the study when I click “register”. I’ve tried this with several separate participant accounts using different email addresses now and it just doesn’t seem to work. However, the mock participants do all show up in my participants tab in the project page. Any idea how to solve this? Thanks!
