Four days later still no updated firmware for the single bay v2.x My Cloud even though the announcement includes the v2.x single bay model. Makes one wonder if they made a typo in the announcement and the single bay shouldn’t have been included, or found an issue with the firmware on the single bay unit.
Edit to add: Just noticed another thing. The title for the announcement says firmware version 2.41.116 (12/01/2020) but the text of the announcement states WD is happy to announce the release of Firmware 2.40.157.
