I reviewed ibotta a while ago and this is a new review. I haven't redeemed an offer in a while but I just downloaded the app again and decided to invite friends to sign up. Yesterday I was able to make a withdrawal from my referrals but today low and behold my withdrawals are suddenly disabled. What an inconvenience. If it's fixed I'll continue using the app and change my rating to reflect otherwise, I'm going to do away with it.
