Why do we need to be connected to the internet in Minecraft Bedrock version 1.20.15.01 to play with nearby Android devices using Wi-Fi and hotspot?

In version 1.19, multiplayer over Wi-Fi and hotspot did not require internet access.

In general, multiplayer with Wi-Fi and hotspot has problems in versions 1.20

In the video I sent, I have shown you the multiplayer problem with Wi-Fi and the connection point in version 1.20.62.
