Python tool box batch process not working.

[CarsonG]

I am in the process of migrating my workflows to ArcPro. This involves bringing over some tools I created in ArcMap. One of the tools, adds 5 fields to all feature classes within a feature dataset.  In ArcMap/Catalog I could run it as a single process or as a batch process with no issue. In ArcPro, I can run it as a single process but it will not run as a batch process. Why would this be?

are you accessing batch processing like this is or the tool not working?

[CarsonG]

That is how I am accessing the the batch process but it is for a custom python tool box.

The limitations may have changed from ArcMap, have you seen this?

I see that, "Some input parameters are not supported as batch parameter, including all Boolean (check box) parameters, Field Map parameters, Value Table parameters, and parameters that accept multiple values."

I am assuming it won't run in batch mode in ArcPro because the input data sets are multiple values. Is there any plan in the future for this to be implemented? 

This seems like a downgrade from ArcMap?
