Roon 1.2 plays DSD 128, Roon 1.3 version 196 doesn't [Solved, managed switch flow control]

I guess I’m showing my ignorance but it seems the switch or how the switch is configured is causing the problem, as all I changed is the switch itself (I do realize that weird interactions can occur with software changes) I do not have enough ports on the GST 108, I realize that buying a new 16 port simple switch might be the easiest solution but before abandoning the GS 716T I’d like to know what is entailed to make the managed switch work with Roon 1.3
Thanks
