This has been bugging me past few hours and I cannot find a fix.

Using local network, both same version Bedrock on Xbox One and PC. (v 1.13.1)

When Xbox One hosts - can see and join as LAN from the PC.

When PC hosts - cannot see anything from the Xbox (but can see person logged on via friends). 

It seems there is a setting on the Xbox One that is blocking access outward - but allowing coming in that happened with recent update. It refers to account settings site by MS, but everything is flagged for adult. 

I have tried checking through all the different settings I could find, but no luck. There is a setting somewhere that controls this... it only impacts Minecraft on Xbox One, no issues with Minecraft used on the PC.

I had no issues in the past with my kids connecting from the Xbox to PC - but the last time that was done was several months ago. Recently I have just been connecting from PC to Xbox to help them build their worlds
