Siri won't give directions if not online

Until recently (upgraded to iOS 16) Siri would give me directions when not network connected. It no long does, saying "Must be online" What setting changed? I rely on Siri for directions a lot since I am travelling the country and need to find businesses and I'm not anywhere near my network, just connected to T-Mobile. This happens whether I have 1 or 4 bars showing for cell connection.
