Well bedrock update has been released like 1 month ago, but my friend and I still can't play together on our world on the same platform (ps4) but I can my friend on mobile version. I think that it might be a nat type problem or some random bugs, this thing has been an issue since the old minecraft ps4 version and 4j actually fixed it. Mine is 2 and my friend is 3. When we switched to the old version, we still can join each other but on bedrock we can't and it keep saying 'Unable to connect to world'. Please release an update  or give us a way to fix this.
