windows 11 thunderbolt 4 bug

Hi Mason, On the official Dell specs PDF for the Dell Vosto 7620 it states that the Thunderbolt 4 port supports up to 40 GB transfter speed and is backwards compatible with USB 3.2, 2.0 and Thunderbolt 3:

4. Thunderbolt 4.0 port with Power Delivery and DisplayPort
Supports USB4, DisplayPort 1.4, Thunderbolt 4 and also enables you to connect to an external display using a display adapter.
Provides data transfer rates of up to 40 Gbps for USB4 and Thunderbolt 4.

If the above is true from Dell official specifications I would expect the the external SSD to run in USB 3.2 2x2 on the USB4 implentation on Windows 11. However, Dell won't support 3rd party products. MS will blame Dell, and Sandisk will blame Microsoft. I'll see what they say on the case I have opened. Hopefully it's just an OS bug that will be resolved in the future.

Also if you are correct, which you probably are (and I appreciate your input and the reply), If the thunderbolt 4 conncector I have only supports 3.2 gen 2, then SSD only runs at about 2000 mbs max which is less than a quater of the (10 gbps) supported by 3.2 gen 2.
