If you own a Sony SmartWatch, you may want to ignore the impending update to the SmartWatch app on the Play Store right now. Some users are reporting that, after updating the required app, their watches are experiencing random reboots, notifications no longer working, and random disconnects. We've reached out to Sony for comment, but so far we've heard nothing back.
It appears that version 1.2.33 of the software began causing problems. The current app has now been bumped to version 1.2.34, however it's unclear if this update fixes the problem and allows users to upgrade safely. What is clear is that if you already updated to 1.2.33, and your device was then bricked, you won't be able to update to 1.2.34, as the device disconnects right away.
