We’ve added support for push notifications on macOS, via service workers. This is supported on Ventura and later. We anticipate Apple adding support for push notifications in iOS on iPhones and iPads later this year.
Huh that’s very interesting indeed. I found this issue with posts from before yesterday’s upgrade too, so I don’t think it’s related to that. I’ll rebake (re-render the HTML) all of this week’s posts as a quick fix and will try to look deeper into what’s happening later today. Thanks for letting me know!
