Ok, I already know what's going on, steps to reproduce (on the example of removing a post):

1. open two browsers and open console
2. on the browser a go to your own topic
3. in the browser b go to the home page
4. on the browser a delete/restore your topic
5. the browser b shows console log
6. Refresh the browser a - f5

7.delete/restore the topic again, console log in the browser b not showing up <----

It looks like it only handle events if I connected as first

Nice!

unfortunately live-updating comments and threads still not working https://lemmy.ml/post/39267

The private messages should be working now.

Yep, works now

in version 7.53, when I added a new post from my phone, in the browser on the desktop (even in incognito mode) I received a notification and an automatic entry appeared on the website.

Now it has stopped working, to see new posts I have to refresh the page - f5.

"live-updating comment threads" - not anymore

also something wrong with private message (can't send message)

not working, tested on chromium and ff @dessalines@lemmy.ml

Nice!
