Why can I no longer video call friends with Playbooks, from my Z10?

Prior to a recent software update on my Z10, I had the green video icon attached to people that have playbooks. I have regularly used the video chat feature to speak with several people, but am now unable to do so.
This last software update also disabled my text icon from working, but bell support talked me through a fix for that. Tonight I also noticed that several photos that I'd taken over the last year have gone.
However my main concern is my inability to video call playbooks.

This is news to me. Thanks for the heads up, i'll look into it when I get a moment.
