Trying to play more than one animation of Blender-created .glb character on same skeleton simultaneously but failing

In How do you play two AnimationGroups on one skeleton?, I saw this answer: “If your two animation groups target different set of bones, then playing both animations would just work: the first animation group will animate the first set of bones, and the second animation group will animate the second set.”
In my case, only the latter animation to which play() is called has any influence, with the rest of the body taking the default pose. I’m not expecting for something this simple to be hard to do. Does that mean that something is fundamentally wrong with my model/animations or how they were exported?

This PG is taken from the thread you refer to:

How do you play two AnimationGroups on one skeleton?

You don’t need two skeletons, you just need one skeleton and two animation groups that control the upper and lower body. I made a simple example by programmatically limiting two animations to the upper and lower body, and then playing them simultaneously. eidt: reversal

This shows that playing back two animations that don’t target the same bones works.

In my opinion, your animations define animation data for all bones, not just those corresponding to the upper/lower part of the cat.

If you can provide us with the asset file, we can take a closer look.
