Streaming Error

Hi has anyone else having issues when I’m trying to open live view via cellular connection all I get is the streaming error message. The live view I’m trying to see gets recorded and I can view the history. I’m using an iPhone 7, my wife is using an iPhone 12 and is able to get live view without any problems so it can’t be signal strength etc. I have a number of cameras and a door bell that all show the same error message.
