Cubase slaving to Logic via IAC bus

If anyone has both Logic and Cubase there I could use some help.

Cubase will lock to MTC but the transport will not follow Logic at all whatever I do, the transport goes to the end of the Project in Cubase and just sits there. Syncing Logic to Cubase is fine BTW. Any ideas?

Frame rate makes no difference at all, tried them all using same on both. Cubase slaves to Reaper and StudioOne just fine.
