Where did iOS calendar "events affect availability" move to in iOS 16

I contacted Apple, and after discussing them finding that the option is still available on my Gmail calendars, just not iCloud ones, the conclusion that we came to us that the feature is missing by mistake and that it should eventually return, hopefully, maybe, probably.

Im creating new events in my iCloud calendars.

The 2 calendars where I had turned off “events affect availability” previously will not show this field when I create a new calendar event.

the option to turn back on events affect availability seems to have been moved in ios16 because I can’t find it.

It shows where it should show in my GMail based calendar but for all my iCloud based calendars the option to change this is missing; yet despite being missing it is still off for 2 of my calendars.

it might just be the 12th bug in iOS I’ve found since 16… it seems more likely that Apple just messed it up since the option still shows on my gmail based calendar but it’s only missing for my iCloud ones now.

but because it’s missing and I can’t turn it back on; I cannot change the behaviour of one of my calendars with hundreds of events in it where I had turned this off for summer and now want the option back on.
