But for a few days now, every time I tap on the messages icon it bounces me to the Google store app for their messenger. I literally cannot see my messages anymore!
A workaround is to change the user agent (is that the word?) by requesting the desktop site. Then, the m.facebook.com domain is a bit more tedious to use but it works and I can see my messages. The www.facebook.com domain is unusable on your phone (rescaling is completely broken and text boxes don't work on my phone, so I guess they didn't really do a good job there).
So now I'm stuck using the mobile version of their website as seen from a desktop browser.
Great User Experience!
