I've got an 13" MBP 2017, Big Sur B3. External SSDs are no longer mounting to any of the USB-C ports and worked fine on B1 and B2. Reset SMC, checked Disk Utility and still nothing shows up. The SSDs are good and mount fine on other devices.

Just wondering if anyone else has had this issue with B3. Any recommendations would be great. Thanks!
