Unable to generate Marketplace data

I am creating livery packs for 2024, however have encountered an error when packaging.

I am able to build the files and have them appear in the sim, however there is no Add Marketplace data button available in the Project Inspector as advised in the documentation.

As per The Project Editor documentation (and as per experience previously) there should be a button to add this information so I can prepare before uploading to MSMP for ingestion. However, it is currently missing.

I’ll fully own this if I’ve messed up but this seems to be a kind’ve important thing to be missing when needing to export for MSMP. I’ve looked through all the options I cna think of and cannot see anything I have missed.

Build and export for Marketplace and upload the Package in MCP
The new 2024 doesn’t require the generation in project editor,
You will need to fill the data directly in MCP
