This is due to customization settings from user profile with respect to custom objects.
To resolve, a System Admin navigates to Setup
- Setup -> Users -> Profiles -> (Profile Type with the issue)
- Object Settings ->ScreenMeet Sessions -> Edit
- Field Permission -> Ensure all available boxes are checked (under object permissions)
(If unable to check all boxes, try cloning profile type and customizing profile from there)
Thanks for your feedback.
