After reinstalling the ps5 preview, I am in a perpetual partial login state.  The main menu says "sign into playstation network" but I already am and can see friend counts on the friends tab when they are in a world. 

All pages say sign-in to see your friends realms, or "you cannot join cross-platform games without a minecraft account. 

The main menu sign-in just flashes and nothing happens. All the others take me to an empty view with no login prompt, just the rotating background. Only the circle button has an effect and goes back to the menus. 

I've opened the options that go to a web browser and I can log in fine there. 

Also, ps4 version is fine. It's just preventing the login prompt on ps5 preview which unfortunately is where most of my friends are trying it out so I'm a bit exposed from joining anyone. 

Thanks!
