@DTS Engineer I have noticed that added on iOS 26.1+ is support for URLSessionConfiguration.allowsUltraConstrainedNetworkAccess Can we assume that the current status of Foundation API is that URLSession requests are going to be transmitted through when the app is in ultra constricted mode connection, with networking.carrier-constricted entitlement provisioned and the client is running iOS 26.1 and above? Thank you so much for the support!

@axl411 allowsUltraConstrainedNetworkAccess This property seems to have been added for support on Xcode 26.1+. Hopefully this means that we can use URLSessionConfiguration to control if our URLSession requests can go through with ultra constricted network is being used. Fingers crossed...
