After the latest update, everything has gone very badly. Errors have appeared; the program has started disconnecting from the watch, so it doesn't send notifications or make calls. Also, when I open the program, it closes immediately and sends me error messages. Therefore, please fix this problem quickly, or revert to the previous version, which was much more stable.

If there was 0 stars I'd put 0. With this app it behaves just as an analog watch does. It connects to Bluetooth but will not connect to the phone. I can't personalize anything with this app. I am not able to change the wall paper because it will not connect. can't do any of the other functions that I'm supposed to be using. Unfortunately there is no other app that will work with my watch. I am about to buy me a new watch that uses a different app. This app is ridiculous!!

no bluetooth icon/conn point on watch. Relies solely on app to create a connection between the 2 devices via phones ability to take pic of bar code....which you've already scanned to download app the app to the phone. Spent hrs trying to do something so simple and still haven't been successful connecting the 2 devices. Maybe it's some kind of security protocol , but I will be sending it back to Amazon shortly.
