Hi So I have my iPhone 11 Pro that has iOS 15.3.1, here in Australia I have two providers Telstra(Physical) and Vodafone (E-Sim) when I turn the second line off the live view starts working, it doesn't matter which line I disable it starts working. I have uninstalled the app and re-installed the app, reset the network settings, even restarted the phone on LTE Im getting great speeds over 100mbps. My Ring Door Bell has Great Wifi (-48 RSSI) and there's no issues with download or upload speed Doorbell is hardwired with a ring transformer Rapid Ring works ok but occasionally drop outs.
