Timeline won't launch signals when loaded by addressables on Android

Hello everyone!

I am trying to load a prefab containing a PlayableDirector by addressable. After it is loaded, I bind it's tracks to their corresponding scene objects at runtime. Everything works in the editor, but when I build on Android, the signal tracks won't launch their signals. Every other track works fine.

The prefabs containing the PlayableDirector and the timeline asset are in the same bundle
The Signal track is correctly bound to it's Signal Receiver.
I can manually invoke the signal receiver's events, so the problem should come from the timeline not launching signals.

I'm on Unity 2019.3.0f6
I have tried with the versions 1.10.0 and 1.2.4 of the addressables
