Even though you should get the latest Android Wear 2.0 update automatically (over-the-air starting February 15, 2017), it may take awhile. To perhaps speed things up you can make sure everything relevant is updated & manually check for System updates.
Start by connecting both your smartwatch & phone to their chargers & make sure they are connected (preferably via WIFI).
Ksana Sweep Watch Face users can now – since version 1.2.0 – add a custom text to lower top content area (the area just below the logo). Plenty of requests lately from users about being able to add their name, location, slogan & such, so I thought it was time to implement it.
Ksana Sweep Watch Face now has full compatibility with upcoming (February 9th) Android Wear 2.0 system update. Also, no phone will be needed anymore. Ksana will be fully standalone. Only a few of the built-in complications (Unread SMS, Missed Calls & Phone battery) needs a phone with the Ksana Sweep phone app to work, and – since you can add any data (complication) from other installed apps on your watch to Ksana Sweep – that won’t be a big loss.
Got quite a few requests to add color to the different ambient/dimmed modes on Ksana Sweep watch face. I’ve been a bit stubborn and refused to make this change because I believed it would hurt battery life and perhaps be hard to implement without risking burn-in on users watch screens.
I was wrong (to my defence the ambient mode documentation available is bit confusing and contradictory).
