I have been using FM Go on iPads for a few years for gathering field data for wildlife research.  We collect genetic samples and they are enclosed in an envelope that contains a barcode for easy entry.  It has worked perfectly until I updated to iOS 10 and FM Go 15.  The barcodes are type codabar.  Any ideas on how to fix this?

I think this is related to your system as I stated in your other post.

I would also check to see if this meets the requirement of your Bar Code software/plugin.
