You should wait from 24 hours. So when I have the right amount of coins to redeem, I just get it. :)
I guess this is what everyone has been complaining. Cashwalk won't let me redeem rewards more than once per day. I think the rule changed a long ago.
I even changed my date on my phone to see if the redemption will work. ๐คฃ It's not working. ๐
