Have you been having problems with multiplayer in Minecraft 0.8.0? You're not alone, many players (including us in our tests) have been having problems. Mojang has acknowledged the problem and has released an update to fix it. Minecraft PE 0.8.1 adds no new features, but does add many helpful bug fixes related to multiplayer and Pocket Realms. The release also fixes issues with keyboard input on Android, which frequently causes nothing to be shown while typing in-game.
The update has been submitted to Apple for review and will be available in a few days. The update is already available on the Google Play Store, but has yet to show up on Amazon's App Store. You can see the original tweet from a Minecraft PE developer in the source.
