I had to unplug the EX2 during an evacuation a few weeks ago (CA wildfires …) and after plugging everything back in again, the shares are now missing, although the Users are still intact and the on the Home screen of the device, the drives are showing healthy and full of data (only 65GB of space remaining.
It is updated with firmware 2.4.155
My previous mappings of my Shares locations are no longer working either.
