Do the USB 4 ports actually work as Thunderbolt 3 too? I know the post is about the Z-series. Perhaps somebody already knows... It seems the AMD-based T14 Gen3 Thinkpads actually don't support Thunderbolt. Some people speculated, it is a firmware matter on AMDs side and will be added in the future but that doesn't sound reassuring at all to me. On the product pictures, you can clearly see the Thunderbolt lightning logos besides the USB-C ports but that doesn't mean anything.
