Sorely Needs a Revision; Problems Began in Early 2016

I loved this app until … something broke in early 2016. Now core functions of the app, like the ability to send messages(!), are broken. I cannot attach photos. Its usefulness is out the window. The last revision was in 2015. Might a new version be on the way? Sadly, I’m looking for anoither app to run Facebook Messenger outside of a Facebook browser tab.
