Check out the developer guide on how to contribute to PyPDFForm: https://chinapandaman.github.io/PyPDFForm/latest/dev_intro/
It is difficult to make sure that PyPDFForm supports all the PDF form creating tools out there. So if you run into a case where PyPDFForm does not work for certain PDF forms created by certain tools, feel free to open an issue with the problematic PDF form attached. I will seek to make PyPDFForm support the attached PDF form as well as the tool used to create it.
