@cdoremus @kissane The problem is that the official app doesn't support it.
Whether we like it or not, the vast majority of "normal people" do everything on smartphones, and if the app can't do it, they won't do it, as having them sign on with a browser is just making it needlessly complicated.
The Web UI for Mastodon is mostly *great*, but the official app lacks so much stuff and also uses different terms for stuff which is frustrating.
IMO, there should be a push for feature parity here.
