Why was the reward for this AI agency task given when the principal amount was lost? Here's what happened: I staked 20u for a month and received a 2u reward. When I tried to withdraw the principal, the system prompted me to解除代理 before I could collect the principal. After解除代理, it turned into this and I can't find my principal anywhere. I asked customer service, and they didn't know either, telling me to contact the operating institution myself. It's not about how much money is involved; this is not right.
