Freezing screen

I absolutely love reading on wattpad but recently my screen has started to freeze when I get a notification or at random. This is the only app that this glitch happens. Ive tried clearing my notifications for the app itself out, but that didnt help. I do not know what to do! I have read that I am not the only one experiencing this and I am very upset that this is happening. When the app doesnt freeze, its wonderful.
