bug Daily mission time bug?

[QuikShot]

I would like to report a possible annoying game bug that's related to the daily missions. I've been playing this game for many months on my Amazon Fire tablet and for some reason when a daily mission countdown timer reaches 0 the said mission will either grey out its "Claim Reward" button or not show it at all which forces me to goto another screen within the game to often at times wait for the mission countdown timer to reach 0 for a second time. The game will do this every so often and always at random; there is absolutely no way of reproducing this rather annoying game glitch. Is there a possibility of fixing for this?
