Deadline for Receiving Task Rewards

Can you please stop making task rewards expire at the end of each month? Why do you have to be so strict about it? It’s way too much of a hassle when that happens right at the end of the month when I’m already swamped. Once I receive them, I have to use them up right away. You’ve gone out of your way to make things inconvenient just to push people toward in-app purchases, so at least be a little more flexible with the rewards for completed tasks… Seriously, this level of unfriendliness is unheard of in Japan…
