Q: Has anyone else had a problem with files going missing in iCloud?  I'm use Scanner Pro which saves files to iCloud and some of my older files are MIA

I use Scanner Pro, which is a document scanning app.  It scans (takes a picture of) the documents then saves as a "spdoc" and uploads to iCloud, then retrieves the file when you need to view or send.  I had some important tax docs saved and when I went to open them today they can't be retrieved.  The folder containing the files shows the the space is allocated for the files (says folder is 8 mb and the files I can see in the folder are only taking up 6.2 mbs). 

Is there anything I can do to retrieve these files.  They are super important!

Thanks for your help!
