My Watch has been misbehaving lately--won't reconnect with the phone after they've disconnected due to distance. That runs the Watch battery down RIGHT NOW. There was something going on inside Bluetooth.
And today, after the update I noticed that half the Wearable app was grayed out.
I finally decided to wipe the cache partition on my phone. That *seems* to have made a positive difference. The jury is still out on the battery life.
Just got mine this morning. The Edge Apps panel changed. Has option to show 4 recent apps at top, but certain apps are no longer available to add to the Edge Apps. I had Instagram previously but it's not available now.
