Hello.. I completed the mission verification on the day of the challenge, but I didn't receive the refund, so I checked just now and found that my progress is only 60% because I didn't click on "3. [Live Recording] Starting 4-hour study session from 2 PM!" In this case, would it be difficult to get a refund? (It was my mistake 😭😭) Separately, I was able to focus happily for 4 hours on the day of the challenge and it was very helpful. I will participate again next time. Thank you^__^
