GLB import in After Effects: shape key animation not playing

I’m running into an issue importing a GLB file into After Effects and would appreciate any guidance.

Setup:

• Blender 5.0 (exporting GLB / glTF)
• After Effects 26 (importing GLB)
• Character animation includes:
  • Armature (bone-based body animation)
  • Shape keys (eye blinking on head mesh)

What works:

• The GLB imports into After Effects
• The armature animation plays correctly
• If I export multiple actions, AE detects multiple animation clips

Problem:

• When exporting a single combined animation, After Effects shows only one animation (as expected), but:
  • The shape key animation (blinking) does not play at all
• In Blender, the animation plays correctly (body + blinking together)

Export settings (Blender):

• GLB format
• Animation: ON
• NLA Strips: OFF
• All Actions: OFF
• Shape Keys: ON
• Always Sample Animations: ON
• Force Sampling: ON

Question:
Does After Effects currently support shape key / morph target animation in GLB files?

Or is it limited to armature-based animation only?

If shape keys are supported: Is there a specific export or baking workflow required to make them work?
