Error: I cannot download LLV or PDC files using Chrome or Firefox on iOS

In Chrome you get the message ‘download failed’ while in Firefox you get a message saying it can’t download the file and asks if you want to open it in another application (but Safeguard Viewer is not available in the list).

You MUST use Safari to download files because neither Chrome or Firefox for iOS have a built in File Manager and can only handle known file types through their own application.
