Glitches

I firstly just wish to say I love the app, but recently I accidentally pressed my home button while doing a challenge and when I tried to come back into the app it goes to the home page for a second then goes straight to the game I was playing shows the question and "time up" on it then goes to the option page of choosing a challenge or theme or whatever its called. It keeps doing this even when I clear it off my background, and wont let me do anything. If theres someway to fix this itd be much appreciated!
