Can't connect to the Minecraft world of my friend on PS4

So basically, since it is now possible to crossplay with PS4 and all other Bedrock platforms, my friend on PS4 got really excited, and wanted to try it out with me (I am on Windows 10 Edition). So he did what he was suppost to, created a microsoft account, linked it, added me as a friend, I accepted. All that went really well.

After he created a world that had multiplayer on, I could see him in the "Friends" tab, 1/8 players on the server. I tried to click it and join. It was loading for a bit. It said "Connecting to Multiplayer" or something like that, and after a while, "Can't connect to world".

Any help?

I play on Playstation and im trying to log into my Microsoft account so I can play with my friends on Xbox but it keeps telling me “We tried to sign you in to your Microsoft Account, but something went wrong.” What do i need to do to fix this problem!?

Having the same problem for the past couple days. Was once in a world with a friend but now and then we get kiked out, so the friend restarts his internet and everything then it works but switches off after awhile again. We had longer games playin late at night. But now cant join them all together

Same for me and my friend, I'm windows 10 edition while he's on ps4 trying to connect to my world. It says "can't connect to world". I can't believe this problem has lasted this long.

Im having that same issue and i cant go online and play with friends  it keeps saying my account wont let me but the settings are set to allow me going online.
