Signals Notebook: I am unable to upload files from an instrument into the application

When trying to upload a file from an instrument using the 'File Upload' feature the file is not shown in the folder's list of available files, but the file is indeed in that folder and can be opened by other applications.

Solution: This happens when the tenant is configured with 'White list only' and the file type (extension) has not been added to the list of file types allowed. Contact your tenant's local administrator and request them to add it.
