Ah, in the Network > Settings > Events Settings, there’s a single option to hide the tabs on different sites. Someone had set the APIs tab to hidden on the network, hence not being able to see that tab.
Can you please update the documentation to add some multisite specific information relating to this issue?
Additionally, the Events Settings and Events Help section being in the Network > Settings section I think is confusing as the Events Settings and Events Help sections are in the Site > Events sections on all other sites. I think it would be a better user experience to create an Events menu tab which holds Events Settings and Events Help just like all of the sites do to ensure a consistent and streamlined experience across both Network and Sites.
Thanks,
Tom
