How many 808 coins are you guys staking with and how does your coin control look ? It sometimes takes more then 8 days. For me it takes 8 days I oon my wallet every 8 days for my reward and often leave it on for two days till it goes through. I think it's about your weight. Bit I can't help untill I get more info from you guys.
I'm staking with just four small amounts: 800, 4100, 2800, 4499.
It could take 6+ months to stake those small blocks. Block size = mining power. PoS is mining. The amount needed to stake quickly, fluctuates with the PoS difficulty. No penalty for large blocks, quicker staking means more compounding as well. I try to at least have hundreds of thousands in each block if not 1 million+.
