Describe the issue you are experiencing

I have an Iphone 13 currently on IOS 18 firmware. I am not able to log in on the HA companion app, it just sits there saying it can't connect. I cannot log in on the iphone via the safari app either. However on my iPad which is on IOS 17, I can log in just fine either via safari or via the app. I have discussed this with Bruno Pantaleao on discord (listed as issue 3194), where he attempted to help me via various options (clearing front end cache, resetting, changing user ID, deleting server etc). Nothing worked.

Describe the behavior you expected

When upgraded to ios 18, you should not be able to login via the HA companion app. It just shows the attached screen. Clearing the front cache/resetting/changing user id/deleting server/changing round internal/external URL should have no effect).

Steps to reproduce the issue

1. Upgrade iphone to IOS18
2. Attempt to login via HA app
