View this encrypted message on your phone?

Recently, whenever my wife sends me a text message, it has started appearing in DIGITS (desktop) as “View this encrypted message on your phone.”  Why would this have changed?  Having to view messages on my phone rather than in DIGITS for me defeats the entire purpose of using DIGITS. (And don’t get me started on the inability of DIGITS to receive messages from ‘short code’ numbers!!!)

Messages used to come through as readable from her.  She sends them as she always has, though I did get a new phone about a month ago… though I don’t see how that would effect the way I see the messages in DIGITS.
