It seems that branle isn't maintained anymore.
What a choice I made to try this out. LOL
I've moved to a different client and now I can see "notes" (I believe that's the proper name?) in my feed.
Thank you!
I believe Branle doesn't have a "global" feed where you see events(posts) from everyone else.
I'd recommend you to try https://damus.io/web/ or https://astral.ninja/. Astral has a lot of features, Damus is getting there too.

a comparison list of some nostr clients is here: https://github.com/vishalxl/Nostr-Clients-Features-List
it mentions platforms too, where they work.
