My watchOS app stops when background mode starts

Hi,

I need some help with an issue,

I made an app for watchOS, it's about a some kind of Timer

I've added the "Background Mode" in "Capability section" in order to force to run the app in background mode, in works perfectly in Xcode simulator.

But the app installed in a real device it works perfectly till the moment when the screen turns off, then my app stops!!!

Someboy has any suggestion in order to solve this issue?

Thanks in advance.

P.D.: I've tried several combinations of pairs "Session Type"+"Modes" but none works for my purpose

Session Type: None Self Care Mindfulness Physical Therapy Smart Alarm

Modes: Audio Location updates Voice over IP Remote notifications Workout processing
