I have tracked this to the new extensions - rather than legacy add-ons. it is no longer registering my panel that triggers the user extensions to be added to the addon

[ronh991]

It seems there was a removal of the GLTF_PT_export_user_extensions panel class

[julienduroure]

Ah, yes, confirmed.

There is no more panel Classes for UI, Blender changed that, and it seems we forgot to update / find a solution for user extension. Investigation in progress

Hello, Blender changes will need you to update all your user extension addon UI. You can see example addon to know how to update:

• There is no more Panel class declaration / register
• Instead, you need to create a "draw" function that let you create some layout panels on the fly See https://github.com/KhronosGroup/glTF-Blender-IO/tree/main/example-addons/example_gltf_exporter_extension

Your addon will also need a manifest file to be able to be installed.

thanks, appreciate the quick response to this issue. Will work on the fix. I have the addon working with the toml manifest file already, just needed your update.
