is how we are using it in the Spark-RAPIDS project (with both scala 2.12 and 2.13). It is not perfect and because of subtitle incompatibilities between it and Spark's CSV parsing it is off by default. We also have a lot of complicated code wrapping it to make it work better. Could you explain what are the issues you are having with it?
