Yes, I got you. I just don’t understand how it’s an “issue” in your opinion. You block any traffic over HTTP from your app so it’s rather obvious that http links will not work.
If you want use HTTP you should modify your Info.plist as explained here: https://pinkstone.co.uk/how-to-fix-http-load-errors-in-xcode/
Don’t know what’s the proper way of doing it from Unity, but you can probably find it in docs.
