I've already used the new Siri for a few weeks but now it disappeared. The Siri app still exists but cannot use. Currently the Siri is the original Apple Intelligence. I went to Settings, Screen Time, Content & Privacy Restrictions, Siri, and the Siri AI (Beta) is grey cannot choose. Anyone knows how to fix it?

So I was using the Xcode 27 beta to do c++ coding. But when I was running the code I cannot type anything in the console. Why does this happen?
