When I start challenges they last more.
I start (on my computer with facebook) challeng for 1 hour and 30 minutes and then I leave poker, then about 10 hours later I play poker on my android phone (and win) and then next they I see challenges completed. That must be bug, because challeng is over after 1 hour or 30 minutes but I complete it 10 hours later.
Hi Alen AlEn. Thanks for bringing this to us. We will look into this and check if there is a bug. Have a great day and enjoy playing.
