I bought this app a while ago and loved it for home school, but now I'm having trouble re-downloading it. Trying to sign in isn't working as well (forgotten password link never sent to email). It looks like if even if I bought it I'll have to buy it again. There are so many one star reviews on here regarding glitches, freezing or even being charged double and not being refunded. It's too bad, because it was great when we used it originally. Don't want to pay for it again - it's too expensive.

I used to like this app but the entire app group and login needs revamping. I was DOUBLE CHARGED $39.01 AND THEY WILL NOT REFUND ME. I PURCHASED THE 10 APPA TOGETHER BUT SOMEHOW THIS ONE THEY CHARGED ME FOR SEPARATELY ON ONE OF MY KIDS PHONES UNDER THE SAME PLAY STORE ACCOUNT. I WOULD DEFINITELY HEAD WITH CAUTION BEFORE PAYING FOR THIS OR ANY APP UNDER DRAGONBOX GAMES. **I CONTACTED KAHOOT. I WAS TOLD TO TAKE IT UP WITH GOOGLE, WHO TOLD ME TO TAKE IT UP WITH YOU., JUST BLOWN OFF BY ALL.
