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.

Paid for the game, made a Kahoot account and tried to access from my kids tablet (family link managed). does not work. Can't link Kahoot account to my paid game. either fails to link to Kahoot account or "reinstall purchased dragonbox " does not work. worst purchase ever.
