Hello Steve,

My question was not "how to change Delta Share ownership?", it was a remark about a wrong information in one of the Databricks documentation.
I don't know if you tested your comment, but of what I have done and has been confirmed by Ashwin, you have to be metastore admin in order to change the ownership of a Delta Share.
If you are only the owner of the Delta Share this is not enough anymore (it was in the past).

Regards,
Loïc
