Vault was created in chromeos Pixelbook and is visible in Android. It is also visible on iPhone.
However, when I use the linux package (installed on ubuntu 19.04 using apt) I initially can connect to my Vault but as soon as I connect its name changes to an id (jumble of letters and numbers and -) and I can see no files. Note that on ubuntu 19.04 the share to Google Drive was set up by setting up google in on-line accounts in the settings panel and I can copy unencrypted files between the pc and gdrive.
Note that in addition to the name of my Vault folder changing to a uid jumble of letters and numbers I have no permission to make any changes on this folder and of course my user name on the ubuntu 19.04 machine is different to android and chromeos (pixelbook).
Any help would be appreciated. Thanks
