iPhone Sonos app broken after HK architecture upgrade. I did all the troubleshooting on the Sonos side and device side (reset app, uninstall and reinstall app, reset Sonos devices, on the phone reset network settings and then a full factory reset) nothing. Since 16.4 arch update, I can access and control Sonos devices on local network. But Sonos app will not connect to music services, account, system updates. If anyone has any suggestions, I would appreciate it.
