The minecraft:burns_in_daylight is added via player.json. The effect works for the host but not client in Multiplayer Game.

Create a new MP game on Win10 with attached behavior pack. Observe that the behavior pack is functioning correctly in world. Player burns in daylight. Join game from Android or iOS client. They behavior change does not seem to apply to this client. Player does not burn in daylight.

Behavior pack files for the former case attached.

Have seen this problem with other behavior components as well, e.g. minecraft:behavior.nearest_attackable_target on husk.
