Ok this is quite a simple bug. Basically just a server bug Im assuming but I try to play with my friend he's on switch and I'm on ps4. I'm the host and he trys to join but no luck in him joining IIke it takes him to that screen where it says * please try again or try again later. If this repeats please check network connection * which I'm sure it is fine. But yeah thats pretty much it please resolve. Sorry I couldn't find a photo i looked online but couldn't find anything. Thanks
