@alland-21: its either celo is not yet redeemable or you have to reach a milestone on celo balance before you can redeem it maybe 17 celos which is equivalent to 1$

@RickGrizzly I have come to realise that opera rewards whoever and whenever they want. It is not a matter of fixed date or time or task. I was like you but today it happened, I suddenly saw the redeem button. My advice is to make sure that you complete all the task every Monday and keep checking and refreshing every hour from 12am to 11pm.
