Guys, what am I doing wrong??
Yesterday at 5pm deposited 10k APEX to my wallet.
PC running all the time.
24hours later, it started Staking.
From the very first moments Staking promised ~20minutes [and the number was slowly falling down] expected time to earn the reward.
But 7 hours have passed from that moment and no profit from stake was credited. Still staking.
Wallet writes now the expected time is 3minutes...

Thanks for your replies!
At this time, we have no reason to believe that staking is broken, as several reports and tests have shown it to be working properly. The estimated stake time shown in the wallet is, like most other PoS coins, an estimate and maybe you have had a bad string of luck. Happens to the best of us. Please keep us informed after another day or so to see if it has worked itself out. Thanks.
