RDS 2019 and Chrome issues

[Sheridan]

We're running RDS RemoteApps on Server 2019 and we have an odd issue, that only seems to affect one user so far (although I bet there's more we don't know of)

 

When running a remote desktop they try and attach a local file to their GSuite email (in Chrome) but it shows the error 'Cannot access \\server\path\...' The network path was not found'

 

The path is valid and works fine for other users remotely, and the affected user when in school. They also cannot drag and drop files to an email in Chrome either, as they see the black circle as if its disabled, but again works when in school

 

The odd thing is, I've tested with several other identical accounts (i.e staff and not admin) and they both work fine! I've deleted the affected users profile on the RDS server but it hasn't helped.

 

No roaming profiles either, so this is puzzling me.
