FydeOS 18.1 for Surface Pro 4 - No working touchscreen

I just downloaded the latest version of FydeOS for Surface Pro 4 and did a straight install, but touchscreen just doesn’t work. Tried on two separate Surface Pro 4 machines, exact same issue on both. When I tried searching online and through these forums, it seems like it works for everyone else just fine. Not sure what I am doing wrong, or not doing right? Please help!
