Hi Regina, Thank you very much for the prompt reply - this is indeed very helpful. I was also testing with v25.2, but on Ubuntu.
Most importantly, it appears there are good workflows for MathML interoperability that are in active use. That is great to see. I will do some more reading of the resources you referenced, and some more experimenting, but am already encouraged!
