I bought a new iphone XR 128 GB today and went through all the steps to set it up like region, language, siri settings etc. Finally it asked me to update ios 14.7.1. Its stuc there for hours with no progress bar. I restarted the phone and it again took me through the entire setup process and again asked me to download ios update. I click on download and nothing happens. It shows estimated time left but does not show any time and there is no download progress too. Attaching screenshot for the same
