Each day a new card challenge is posted and on the 15th there was 2 of them to do. I kept waiting for the 16th to post only later in the day to find it posted in between the two 15's. So now it goes 15, 16, 17, 15.
I just usually scrolled down the list each day to get to the last one to do. I am sure others do as well. Is there any way to get them back in order?
