I've been trying to follow Apple's testing age assurance documentation here. After following each step and setting my user as "Texas, child 16-17, significant change declined", the AgeRangeService consistently throws the notAvailable error: do { let response = try await AgeRangeService .shared.requestAgeRange(ageGates: 18, in: self) // ... } catch AgeRangeService.Error.notAvailable { // Always throws this error }

I'm reading the "Testing Age Assurance in Sandbox" doc, but I couldn't figure out the step: 2. Tap Sandbox Testing from the main menu Where is the "main menu"?
