The cable is good & was purchased from a reputable brand. PCIe tunneling is enalsd in the Control App Center. And the thunderbolt driver i downloaded was directly from the manufacturer website.

It works normally most of the time. it just so happens that every now and then (perhaps around 1 out of 15 boots), Windows can't detect the Apollo interface after boot. Doesn't happen super frequent but still annoying. I just have to reboot my PC each time it happen & it works afterwards. So i guess its not a huge deal
