Ever since my upgrade to 8.1 yesterday may WhatsApp favourites disappeared COMPLETELY. My first time using WhatsApp after the upgrade gave me a notification saying that Whatsapp isn't compatible with my OS. I refreshed contacts and only 10 favourites showed up. Rebooted the phone and refreshed contacts and now I'm up to 246 contacts. This is approximately 2/3 of my favourites. All my contacts are still in place in my people hub. Subsequent refreshing favourites has not increased my favourites count.
I suspect that the problem may lie in linked contacts etc...
My only temporary fix is to manually re-add each unlisted number to the existing contact for WhatsApp to list them as a favourite. I'm guessing I may have to put this forward to Whatsapp support and wait for then to update for 8.1.
