System Calls link is: https://docs.nordicsemi.com/bundle/ncs-3.0.0-preview2/page/zephyr/kernel/usermode/syscalls.html --> not found
the "3.0.0-preview2" is likey the cuprit.
Editing the URL to my current SDK 3.2.1 resolves to a real page:
https://docs.nordicsemi.com/bundle/ncs-3.2.1/page/zephyr/kernel/usermode/syscalls.html
`ncs-latest` -- which is generally what the DevAcademy links use -- also resolves, but has the formatting issues for other ncs-latest pages that I raised in an earlier ticket.
