What changed
The API can now return formula and rollup page property values and property item values with type set to "unsupported" and an empty unsupported object. This happens when a value depends on too many related pages or nested formulas and rollups. The response doesn't include a partial value. Treat the property as unavailable. Rollups still include the function field. To make the value available, reduce the number of related pages or simplify the nested formulas and rollups.
