Created attachment 343834 [details] screenshot in Safari Simple test page for CSS env(): http://output.jsbin.com/qenayuq On my iPhone with AppleWebKit/605.1.15 and Safari iOS 11.4 it shows disabled. Running Chrome on the same device (i.e. same WebKit) it's enabled.

Also tested a different iPhone 6 device and it was enabled there. Explicitly turning on the flag in "experimental features" also makes it work. This was hit when evaluating the web-platform-tests we landed for shipping the feature in Chrome: https://groups.google.com/a/chromium.org/d/msg/Blink-dev/Fim-KmT08PE/LIHNNXALBAAJ

I am not sure on previous version since I have only one device and iPhone 13 Pro Max with iOS 15.6 is showing that CSS env() is supported based on test case in Comment 0. I think since old versions are not supported and only receive security updates, I think this can be closed. Further - caniuse.com shows clearly that it was from Safari 11.3 onward for iOS - https://caniuse.com/?search=env() Can this be marked as "RESOLVED INVALID" or "RESOLVED CONFIGURATION CHANGED". Thanks!
