known bug with ios15 and realitykit anchorEntity(anchor:x) ref: https://developer.apple.com/forums/thread/699266

I need this too. Apple please respond quickly, we have product to build.

Why does a dialog pop up that requires install of new components? This is a) rude to force an update b) this is an upgrade not a component install which is deceptive c) disrupting engineering productivity time loss due to hours of down time d) just mean.

just upgraded my ipadOS app to iOS15 and the AR part of the app is now completely broken. literally no AR functionality works. other than that, an awesome upgrade;) I verified I'm not crazy by installing the same app to iPad8 running iOS14.8 and my AR functionality works fine. broken environment: xcode13, ios15 (prod release), ipadPro working environment: xcode13, ios14.8, iPad8 I think this is worth a zoom meeting to demo my findings with the apple dev team.
