Raspberry Pi 4: Can't send MIDI clock from Digitakt

Hi, I just can't figure out why my rpi4 patch is not receiving tempo or transport. I'm using the metro object. All the rpi4 is updated, audio jack and all. It properly receives and sends midi notes and CC, but not clock. The online articles and tutorials arn't very clear, and even if I try what they say, it's not happening. My Digitakt midi preferences are properly set.
Any help much appreciated!
