With the update of iOS 14, Apple has introduced many new privacy features. With this update, players will be prompted with a notification upon opening Minecraft for the first time.
“Minecraft” would like to find and connect to devices on your local network.
You will need to press “OK” and allow this connection as you will not be able to sign into your account without this permission being allowed. Some features such as the marketplace and single player worlds may still work, however multiplayer and Realms will not be available.
If you declined this popup, you may be unable to login until Minecraft is updated for iOS 14. We are currently working on updating the game however you may encounter this bug until the patch is complete. Thank you for your patience.
