To bring the application data to its original state in Sim, I perform the following sequence of actions:
1. Delete all Apps
2. Kill device
After that, for the next launch of applications, the storage data memory was cleared.
It still works with Fenix Chronos
However, this stopped working for new watch models.
Attention! Question: how to clear the application storage memory without launching it for Fenix Chronos, but directly for the desired watch model.
