I’ve received a few updates from users pointing out this is not actually available on all platforms – though most key platforms have it by now.
Therefore I’m re-opening this thread. However I’d like to include a short “inventory” in order to focus this a bit.
Please feel free to give a short heads-up about the missing platforms in this list.
