Online features are currently not working well

Here is a list of what I found you can't do;

Join online crossplay servers/crossplay worlds

Enable multiplayer mode

There might be a few other but for now this is what I have found

How to replicate:

#1; Go on Minecraft on a PS5 (PS4 and PS5 version of the game are the same)
#2; Try joining a server/multiplayer world
#3; Try creating a new world and enabling multiplayer
#4; Check Realms. If you own a realm, it should say "You cannot play on Realms at this time."
#5; Try joining Cross-Platform friends, it should do nothing and send you back where you were
#6; Try joining friends, it should say "You cannot play online multiplayer at this time." and it says the same for featured servers
