Seems to be a problem with Android 14. It’s already been reported on GitHub.

Almost too much information, really.

But at least it has lists.

Tap “Explore” in the bottom toolbar, then the three dots next to “Subscribed”. Select “set as default”.

My guess would be because of the reach?

I use neither Mastodon nor Twitter (I’ve never understood the value of microblogging) but one of them is freely available, the other one is restricted. In my view – as someone who has no account on either platform and only occasionally goes there if it’s linked somewhere – Mastodon has a much wider reach.

Oddly enough there is a mastodon instance run by a German federal agency: https://social.bund.de/

No idea why the chancellor doesn’t use it.
