Lightening to hdmi

Hi I am new running Zwift on iPhone and Tacx flux 2 all set up ok I then tried a iPhone lightening plug to hdmi and when it comes up on tv it’s on its side and the screen orientation setting is ok and it doesn’t matter what way you turn phone it stays vertical anybody able to help cheers

Does this only happen with Zwift? I often Zwift using a lightning-HDMI connector, and it works well (though once or twice I’ve had to move the phone sharply to shift it to a horizontal view).

Don’t think so will check as soon as my phones updated everything

Same here - I use an iPad and lightning-HDMI connecter and it works like a charm.

I have uninstalled Zwift and updated both phone software and app and still no joy please help
