i type the command /join username but i dont join anyone (im on ps4)
#lfg
upper ice
outer knoll
did you include the numbers in the username?
it should look like this
/join xeryla#0069
slow inlet
Another thing, if your game isn't in English the command can have a different name
/beitreten in German for example
pulsar hollow
yeah, its the translation of "join" into your game language
