+!!! 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:

There is also one below for the v1 `DataFrameWriter` API.
