Cannot Join Cross-Platform Multiplayer: Error ‘Blocks Between Client and Server Do Not Match

Hello, I need help with an issue. My friend and I cannot play Minecraft together even though everything appears to be set correctly. We have tried many solutions, but the issue still persists. Minecraft does not show the other device as online. When Android sends an invite to iOS, it shows the following error: “An error has occurred: Blocks between client and server do not match.” When iOS tries to invite Android, the Android account does not appear online in the invite list. Sometimes it briefly shows as online, but when trying to join, nothing happens. Even when both devices are connected to the same LAN network, the same error appears: “An error has occurred: Blocks between client and server do not match.” I confirm that: Both devices are using the exact same Minecraft version Both accounts are signed in with Xbox Live Multiplayer settings are enabled on both devices Game permissions and privacy settings are correctly configured The world is set to public and invites are allowed Both accounts can add and join friends No mods, add-ons, or experimental features are enabled Both devices are also updated to the latest available version of the game. Despite all of this, the game still does not allow us to join each other. Please help. Thank you.
