I have noticed the same problem. Miles earned appeared in my skywards account more than three days after sectors completed. They would normally show within 24 hours. There are some more problems currently. I booked two flights through business rewards. The future booking and future miles did not apepar in my Skywards account. They would normally show within a few hours after the booking was made. This time they only showed after I contacted Skywards via web form. I guess this was through a manual adjustment.
