Please take a look here where a user described a problem after the update from Season 1 which I experienced myself. I also posted a few of my thoughts what the reason for this problem might be. It's not a major bug - mor a little annoyance but if this could be fixed or at least figured out it would be very nice.

Edit: This has now fixed with the latest update. Thank you!
