I thought that was gone but you’re right, app.ft.com still works and can be installed as a full screen PWA. But the main site, ft.com, isn’t a PWA (or at least, it doesn’t install as a full screen web app). I had assumed they had shut down the PWA, because I haven’t seen any promotion/mention of it for years (and I use ft.com a lot) so I don’t know how regular people would find out about it these days.
