I looked into it a bit more, looks like somebody reported this bug 3 days ago and it was fixed yesterday in version 0.0.32. You should be able to update from the play store or f-droid and then go into Settings -> [account] settings, change the default listing type and tap the Save settings button so it updates the local preferences and once you restart the app it should work

I tried it as well, it did update the default listing type on the app to subscribed. Looks like there is an option in the app under Settings -> [username] settings, but the dropdown seems broken, at least for me

your subscriptions should be listed in the drawer/hamburger menu once you’ve logged in

I’ve heard of Mastodon around the time Elon bought Twitter, researched it a bit, but I’ve never been a Twitter user so I wasn’t particularly interested. My first real interaction with the Fediverse was 2 days ago when I tried Lemmy :D
