Claim Rewards
There is a claim rewards section on Hive-Engine and LeoFinance.io. Do we need to claim the rewards? What happens if we don't? Finally, why does the button only work some of the time?

Not totally sure, but you don't need to claim. Its going to accumulate there until you claim it.

After claim. Wait few seconds-minutes to action be processed in block chain. If you click it and reload the page maybe it's atill there until claim process end.

Works every time with me...
