You don't need to use the official Mastodon apps, they're not the best way to use Mastodon. The official apps only arrived last year, and they were intended as "Fisher Price My First Mastodon" things with a restricted set of features.
Third party apps have been around longer than official ones, and include way more features. You can sign in with the same account on all apps.
On Android try Tusky, Fedilab, Megalodon, Tooot
On iPhone/iPad, try Toot!, Ice Cubes, Ivory, Mona
So let me get this straight. The Supreme Court is only supposed to take cases where there is a real injury and real controversy, but it took the case of a web designer who faked a request by a gay customer for a website design? The guy was actually straight, married and with kids?
Vacate this case.
