After updating to Minecraft Bedrock 1.21.90 on Android, Multiplayer is no longer available.
Even with a Microsoft account properly signed in, the "Invite to Game" button is missing, and LAN worlds are not visible to other devices.
Things I’ve checked:
I'm signed in to my Xbox/Microsoft account;
Wi-Fi is active and stable;
Multiplayer is enabled in the settings;
All permissions (internet, local network) are granted.
This issue started immediately after updating to version 1.21.90.
Other players have reported the same issue — Multiplayer simply disappears even when everything is properly set up.
I can confirm the same.
I have 2 android devices, one 1.21.90 and one 1.21.82.
1.21.82 → Network button on World select screen is present (toggles LAN worlds)
1.21.90 → Network button on World select screen is MISSING
Therefore you cannot view or join a LAN world.
You can, however, still specify multiplayer settings when creating a world in 1.21.90, it’s just not visible / joinable.
Since updating both devices to 1.21.92, the network button is still missing and I cannot see or join any LAN worlds.
