I need to reconnect a few times to make it work, or sometimes only reboot helps. Step to reproduce 1) sleep mode laptop 2) connect the TB dock 3) laptop will wake up itself. 4) got only main(laptop) and DP master monitor works My setup looks like laptop->TB13(dock)->1-MasterMonitor->2-SlaveMonitor. This is not always happening! But still quite often.
