good evening

There could be several reasons why you can't connect to your friend's world in Minecraft Bedrock:

Firewall or router configuration: Your firewall or router may be blocking incoming connections, which would prevent your friend from connecting to your world.

Internet connection: A slow or unstable internet connection can prevent you from connecting to your friend's world.

Game version mismatch: You and your friend may be playing on different versions of the game. Ensure you are both on the same version of Minecraft Bedrock.

Xbox Live account: Make sure both you and your friend are logged in to Xbox Live, as it is required for multiplayer on Minecraft Bedrock.

NAT type: You may need to change your NAT type from strict to moderate, or open, in order to connect to your friend's world.

My world synced Every time I saved it, what is the point in playing the game if all progress can just be lost!!! It's a complete waste of time, they can't tell me how the world got corrupted which means it's absolutely pointless playing Minecraft as at any
point the world can disappear

Guys why i can't join in world of my friends on Minecraft?
