5 star app but it keeps freezing

Look Ive had this app for about 3-4 months, and I know how to use it! But today its been acting up! I would try to change my specific word to a different font, size, or color and it freezes! I have restarted my phone to see if itll work and I have refreshed the app! But other than that this app is definitely awesome for adding text to pictures!
