My friend and I cant play together AT ALL on the PS4. Every time he tries to join my world or I try joinin his, the “Unable to connect to the world” message appears. We both have fine connection and NAT status, we obviously have the last update installed and we used to play together all the time, last time we played was back in December. Its really infuriating how we cant for the love of God connect due to your endless bugs, Mojang. 
Please get a workaround for that glitch that has been out there FOR SO LONG and you guys just seem to not care about it at all.
