Custom Options update on import

[tony_parker]

Hi All,

When I try to upload a CSV with custom options (to update existing products) all fields bar the custom options update. I have tried all the obvious stuff like changing the delimiters and "quote all fields" but with no luck.

Is this a know issue? I'm on Magento 2.3.3

Thanks in advance.

Anyone had this problem? I've broken it down to as basic as it gets and still nothing. CSV Below:
