Unfortunately, I have too many layers of security.
Can you just explain the steps for adding a file properly to a Dynamics Content page?
When adding a Dynamic Link to a page, there is a field to modify the Link Text.
When adding a Dynamic File to a page, there is no field to adjust the Link Text for the file.

Using Dynamic Text to display files feels like a hack. There should be a Dynamic Files add-on to choose from that is specific to files. Please tell your Devs to create this and make it much easier handling files.
NOTE: Default Text is only if the field is empty, not the name of the file!
