Vibration Stops Working After PC Charging using v15.74 or v15.76 Software

We faced with a very serious problem. Watch (tactix 7 and Phoenix 7 maybe other models too) looses vibration after charging or connect watch to a computer. All kind of vibration stop working untill reboot. So it's unacceptable to reboot watch each time after charging. If you forget to do it you won't wake up at the morning becaouse your alarm watch is useless without vibration.
