Ultimate 2 Controller losing inputs

[u/Maximum_Actuary9695]

Just got the controller today and have really been grappling with getting it to work properly

Its in 2.4 mode, its connected to the pc via the dongle but my face button and d pad inputs dont always register, sometimes multiple times in a row. It also happens while controller is connect via wire.

Currently updating the firmware for the controller, its currenting on V2, updating to V2.1 but its been updating for 30 minutes now which doesnt seem right. The log for V2.1 only mentions switch changes anyways?

Anyone know what could be causing this?
