I will do the test, but my Zorro S subscription was ending with 2.70. My setup (framework of many .cpp 64bit files + Python Gui) is running with Zorro-S functionalities. I had my errors in the beginning via trading (missing historical data during the LookBack), but then I recognised the gaps during the loading (Download script) of historical data.

Therefore, I have to test with the Zorro Free account, but I will do. I will use your script.
