The "Add record" and "Add milestone" controls are disabled in our Gantt view. Removing all filtering, all grouping, and disabling/re-enabling "Use milestones" in the view's settings have not helped.'
How is this supposed to work?

Wonderful, thanks so much @TheTimeSavingCo.
There it is! That's a bug. Or, at least, this is a broken expectation. A computed end date is the reasonable approach when defining task duration using a start date and duration. I'm hoping it's an oversight and not some implementation detail which is preventing addition of milestones and records.
Any chance we can get the attention of someone who can affect change?
Perhaps you could make use of the new Date Dependency feature? https://support.airtable.com/docs/date-dependencies-in-airtable
It's basically the exact same functionality you're looking for, except with a Date field instead of a function field?
