I am using the Sensus app to assess mental health and activity levels but I am running into some issues. The protocol is set up, however, whenever I attempt to start it and click submit, the progress bar does not go past 50% and then freezes or crashes. Is this a problem with my settings or is there anything else I'm not considering?
This is my protocol URL: https://www.dropbox.com/s/frcynz07i3t72js/13.json?dl=1

Any help would be appreciated!
