Win10 Pro 1803 will all available updates. Dokany vault created in Dropbox.
I received the notification that 1.4.11 was available for download. So, I closed my vault mounted at X: and exited out of 1.4.10.
I ran the installer and then unlocked my vault. When I went to access it, I got an error message saying that the drive (X:) was unavailable. (Unfortunately, I no longer have access to the message I received.) When I looked at “This PC”. It showed X: as a local disk with 0 size. When I looked at the options for my vault, the mount point was set to “assign automatically” instead of X:.
To get it to mount at X:, I had to force it to mount with automatic drive assignment (which worked) and then lock the vault again. At that point, I could change the vault drive letter to X:. Once I did this, it worked as it had before with 1.4.10.
I’m not sure what the installer did during the upgrade to break this. But, it definitely broke something temporarily.
