Hi! I have set up a money pool fundraiser to collect money for my kid's teacher's bday. I am aware the service is being discontinued but that's not the issue, it's still on for long enough for this particular occasion. However I am baffled about the fees. I was under the assumption that money pool is free of charge but now I'm getting deducted a 20 percent fee from every contribution I am receiving. That's pretty outrageous imo. What am I missing?
