Just now, loading the page https://lemmy.world, I saw a different user’s main page. The page loaded in light mode (I use dark) with the username of /u/froodloop in the top right. Then a moment later, it refreshed into my expected main page with my username in top right. This went past too quickly to get a screenshot, but it was reminiscent of some of the bugs that were happening in the old websocket code.
To send a mention use type
@user@instance
and select from the dropdown box, alternatively type the full link manually[@user@instance](https://instance/u/user)
You can generate an instance agnostic link with
/u/user@instance
automatically, which will allow other users to see their profile from within their own instance, however this won’t give a mention notification to the user.@froodloop
I’m not sure if the link text has to be correct for the mention. When you select from the dropdown box on lemmy it comes out with @user@instance in the link text.
Also I edited my comment above to include instance agnostic links. Unfortunately they don’t deliver mention notifications.
