New Watch UI makes using watch difficult for running

Please revert the recent watch UI changes back:

1. The disappearance of the "3 2 1" countdown (Unacceptable Problem): Removing the countdown timer is a disaster. Now the start of the race has become cumbersome, lacking immediate automatism and forcing unnecessary intermediate passages that waste precious seconds. You can no longer use it literally. If you really wanted to change the interface, you had to Make it optional in settings, giving users the choice! Removing it completely was a wicked choice.
2. Total loss of essential data and horrendous interface: The new sports bar is a huge step backwards. In the GPS symbol, you can no longer see the status of your heartbeats to understand if the sensor is connected or not. Before, a glance before leaving was enough to verify the synchronization of the sensors, now total ambiguity reigns.
3. The blocking bug of the back key: During your running session, if you press the physical button to go back with the intention of scrolling through the various activity screens (to check splits, the map, or the graphs), the workout instantly pauses and freezes. It's inconceivable: you can no longer consult your data on the move without forcibly stopping recording.
