EOS 5D Mark IV iPhone 15 and Canon Camera Connect issue

[Sentosa]

Hi everyone. I have just upgraded my iPhone to the new 15 but find when I try and connect to my 5D Mkiv the app fails to connect at the same time the wireless signal on the camera screen shows an i alongside the wireless transmitting icon. Given the iPhone 15 is the latest release I am assuming its iOS that may be the issue, or; if it is a common issue any advise on how i rectify the issue?

The App is Canon Camera Connect.

Try completely removing the configuration in both the app and on your 5D IV and start over with a brand new configuration.  I've had to do this with my 5D IV whenever I get new iPhones.
