Motorola’s Moto 360 still has yet to receive the big update to Android Wear 5.1.1, and apparently that’s for good reason. According to a recent tweet sent out by Motorola Mobility in response to a curious 360 owner, the update still isn’t ready for the Wear device because of performance issues. No specifics were called out in the tweet, so we’re not quite sure what exactly is holding Motorola back from unleashing the update.

@davidcstevens_ Performance is not quite there yet. We’re working with Google to ensure the software works great on #Moto360. Thanks.

Of course, many owners will be upset that their devices haven’t gotten the update, but it’s good that Motorola is working with Google to fix the issues before sending it out to the masses.

For those unaware, Android Wear 5.1.1 brings many new features, including the ability to set always-on applications, new gestures for scrolling through Google Now cards, and a much more refined contacts/app menu. The update also brings Wi-Fi support, allowing compatible devices to receive notifications, as long as your watch and your phone are both connected to a Wi-Fi network. This update is the biggest one since Android Wear’s inception, so hopefully Motorola can get things sorted out in a timely fashion.
