!!!! So im not the only one having this issue. Mine just started doing this as well and was just about to make a topic for it but saw yours. Ive tried restarting everything (ps4, modem, router) even deleting the save options because that fixes the ui issue but nothing seems to work.

Half the time I get the vanishing channels when I try to join them problem you have, the other half i get an empty lilst with the voice chat is unavailable error message.

Mine hasn't worked since i bought the *** game smh its really annoying when you're trying to pvp or talk with guild mates.

Still not working. Bump!
