Micro Focus Filr 3.3
Micro Focus Filr Mobile app for iOS 10.3.3
When viewing any Filr-based .pdf from an IOS mobile device, the following error is displayed:
"Unable to view file"
When you choose the option to "generate preview", the error repeats.
The same file can be viewed from the Filr web interface.
A fix for this issue is available in the Filr 3.4 Update. With the fix in place, the Filr Mobile app for iOS will utilize the Quick Look framework for previewing PDF files that were previously being rendered using the Filr server's HTML Preview mechanism.
It is possible to open the PDF in Acrobat on the IOS device, however this requires more steps for the user.
