Before reaching out to support, take a look at this: [BUG-13715,13982] Perspective App - #19 by mrojas
If there are any reverse proxies or other middleware between the Perspective App and the Gateway, make sure that custom HTTP request headers are not filtered out before forwarding to the Gateway. I believe these include:
- client_timezone
- device_id
- device_type
- version_code
- perspective-session-id
