Hey,
On my personal instance it is automatically set up so that when creating a new service in JSM you can also add responders or stakeholders:

When checking a much mature cloud instance I do not get the option to add stakeholders and responders:

Slightly confusing as both are cloud deployments of JSM so all updates are automatically rolled out. But it seems like the mature instance is not up to date with the latest features. Could someone let me know if they have experienced this?
I have cross-checked both instances and cannot see any settings etc that could be stopping this from working.
Thanks in advance.
