+!!! Warning
+    When reading with DataFrames in Spark 3, use `table` to load a table by 
name from a catalog.
+    Using `format("iceberg")` loads an isolated table reference that is not 
refreshed when other queries update the table.

Review comment:
       Thank you, @rdblue . It looks good to me.
