There is a chance that this is still a “disabled for now” feature.<p>My understanding of the third-party browser requirements in the DMA is they have to be able to do anything Apple’s Safari can do if they want to, and while Apple’s built out a bunch of entitlements for browsers and other DMA requirements, they haven’t done the same work for PWAs. Yet?<p>So given that, it would actually violate the DMA if Safari supported them but Chrome and Firefox couldn’t, and they’re not going to allow that until they’ve taken the time to figure out how they want to proceed, if at all, with allowing it for third-party browsers.
