I did not. I didn’t have an iPhone to be able to get onto the settings with.

That’s the most iOS looking app I’ve ever seen on Android. Not a fan. Sorry

Favourite and Bookmark are absolutely different things. They’re two different lists for you to use as you see fit.
Neither of them is a Like though. I’m not sure that fact is really debatable.

Mastodon doesn’t have Likes at all.

The star you’re referring to is Favorite. Those go into your Favorite list. So you can refer back to them more easily.
