I can’t add text – Stop Motion Studio Pro Review

I absolutely love this app. But when I started doing a story thing I wanted to use words so they could talk. But it won’t let me add text! I used YouTube, looked on google but it didn’t say anything helpful. Plus they were all about Stop Motion Studio (not Stop Motion Studio Pro) and it was really painful. I still can’t figure it out. If it helps I have and IPhone S6. Please help me out.
