System Information
Operating system: Windows 11 23H2
Graphics card: Nvidia Geforce RTX 3080

Blender Version
Broken: 3.6.12 (LTS)
Worked: Never worked

Short description of error
If an object has the "Link" dropdown in the material properties set to "Object" instead of the default "Data", the FBX exporter will export that object's mesh without shapekeys.

Exact steps for others to reproduce the error

Open the included test file.
Observe that the cube has one shapekey and has the "Link" dropdown in the material properties set to "Object".
Export an FBX (default settings are fine)
Inspect the resultant FBX in Unity or whatever program and see that it has no shape keys.

Now go back and change the "Link" dropdown to "Data" (default).
Export another FBX (default settings are fine).
Inspect the resultant FBX in Unity or whatever program and see that it has shape keys as normal.

Can confirm for blender 3.6.4 (or like your described 3.6.12), but seems to be fixed since blender 4. I tested it with blender 4.0, 4.1, 4.2 and it works just fine. See the attached .fbx output files for blender 3.6 and 4.1.
Also according to the documentation shapekeys support is very limited in blenders importer/exporter...
