Q: Can't see what I'm typing on Facebook Messenger

I recently switched from an iPhone 3 running ios 6 to an iPhone 5 using ios 9. Now when using the Facebook Messenger app, I cannot see what I am typing or the rest of the conversation. All I can see is the keyboard, with a tall while block above it. I can't see what I typed unless I exit the conversation and then go back in. But as soon as I type one letter, the white block appears. Nothing in the phone settings or app settings seems to help, and I cannot find any answers on the internet. Apparently other people are having the same issue, and can't find answers either. It is very frustrating to not be able to see what I am replying to, and even worse not to be able to see what I am typing. Please help!!!!!
