Cloud shell: Warning: Failed to mount the Azure file share. Your cloud drive won't be available.

Due to a number of limitations in my current environment I have been using cloudshell on a regular basis. Recently I keep getting this message (bash):

Warning: Failed to mount the Azure file share. Your cloud drive won't be available.

Your Cloud Shell session will be ephemeral so no files or system changes will persist beyond your current session.

Or this one (powershell):
Your Cloud Shell session will be ephemeral so no files or system changes will persist beyond your current session.

The thing is, the clouddrive shows as mounted, I can write to it and the changes are persisted. I'm just worried that sometimes they won't be and I will lose data. I have tried running clouddrive unmount then remounting both my existing file share and a new file share but still get this message. I also tried the "Reset User Settings" option but it does the same.

It is also inconsistent, it seems to appear for a long period then disappear for a long period.

Anyone else seeing this? Any suggestions for a root cause or what can be done to ensure the drive is definitely not ephemeral?

    @Michael Cameron I got the confirmation from the internal team - "The error was due to a bug where one step in the mounting process is failing but the rest of the mounting operation completed successfully. We have a fix for it that will be included in the next Cloud Shell image update."

    The image release with the fix completed on July 23rd.

    SMB channel encryption was my issue.

    AES-128-GCM had to be enabled

    having just AES-256-GCM enabled to setting to maximum security caused the clouddrive to not mount.
