I'll give this app all 5 if I can figure out how to upgrade the subscription. Yes, nothing works. Website's instruction is so misleading. Doing so in an ANDROID phone does not have an option to do so. It only has a resubscribe link. When you click it will only resubscribe you to your previous plan...no option to either an upgrade or a downgrade. I cancelled my subscription. Now I have to wait till the end of the plan. Then hopefully, I can upgrade...till then just 1 star.
