It sounds like you're encountering a sign-in issue when trying to link your Microsoft Account to Minecraft Dungeons on the Switch. Here are a few troubleshooting steps you can try:
- Check Sandbox Settings: Ensure that your device is set to the correct sandbox environment. If you're using a test account, it should have access to the same sandbox that your game is published to.
- Verify Account Access: Make sure that the Microsoft Account you are trying to link has access to Minecraft Dungeons. Sometimes, accounts may not have the necessary permissions to link.
- Clear Cache: If possible, try clearing the cache of the game or restarting your Switch. This can sometimes resolve temporary issues.
- Update the Game: Ensure that Minecraft Dungeons is updated to the latest version. Sometimes, issues can arise from using outdated versions of the game.
- Check for Multiple Logins: Double-check that you are not logged into Minecraft Dungeons on any other devices, as this can sometimes cause conflicts.
If you continue to experience issues, consider reaching out to support forums or the game's customer support for further assistance.
