ActivityMonitor.xxx not working in simulator anymore

Good evening,

I've been testing 

ActivityMonitor.getHistory().size() > 0
 for years before accessing data like ActivityMonitor.getHistory()[n].activeMinutes.total (with n < size) but starting tonight, using an "old" watch face code, the test is always false, even when I fill in the Activity Monitor Info of the simulator. And if I try to bypass the test, I face some Out Of Bounds erros when accessing activity monitor data (i.e.ActivityMonitor.getHistory()[0].activeMinutes.total to get yesterday's active minutes) Sweat

I am using SDK v4.0.9 with VSC and a Garmin 6S Pro watch on the sim.
Funny thing: the watch face with the same code is running ok on my actual watch Astonished
Did I miss something? Thank you for your help!
