Op-z MIDI Thread

I’ve been happily using a usb-C to usb-B cable to send midi to The intellijel uMidi Eurorack module directly from my op-z. (badicaly without the oplab!) It stopped working after the last op-z firmware update in April 2020. I’m curious if it’s a known issue or it’s just a freaky coincidence that either my uMidi module or the cable is broken right after this update. Anyone?
