Can you daisy chain with the second Thunderbolt port?
For products with two Thunderbolt 3 (USB-C) ports, the second Thunderbolt 3 port supports Thunderbolt 3, USB 3.1 (10 Gbps), and DisplayPort devices. You can daisy chain up to 6 Thunderbolt 3 devices in a daisy chain but the devices in the front of the chain have to be turned on in order for the other devices to be recognized.
