I wonder whether there’s a difficulty in Apple about how much power to give web apps in light of their privacy play. The browser isolates permissions - Facebook can let me upload a picture in a chat without giving them permission to all my pictures, their app can’t or at least doesn’t. If they had notifications working for PWAs I’d probably drop Facebook Messenger for example.
