Every time my friend and I go to play, neither can enter each other's world.

Hello good afternoon. Well the bug I'm going to report is that when I enter my friend's world it only appears "it was not possible to connect to the world" even if she or I creating the world this appears, I've tried everything I know but it didn't work, we're on the same version, microsoft accounts connected to the game, and original minecraft from the play store, both play on android minecraft bedrock, i really ask you to fix this bug, and i realized i'm not the only one with the problem.
