We've run into this issue as well with DLT (Autoloader under the hood). Unfortunately, I don't know if there is a definitive answer out on this yet. The closest thing I got on my post is that: "Autoloader, in general, is highly recommended for ingestion where the files are immutable."

Didn't love that answer to be honest, after all I would expect that if the feature is available it should work as advertised.

Is this still an outstanding issue? Have you had any luck getting this resolved? I'd be curious to get a better understanding of the root cause of this.
