### 5/5 — 팀 코코넛! 항상 응원합니다!

*2025-11-22*

코코넛 팀을 남몰래 응원하단 중 볼트 출시 이후 아묻따 바로 질렀습니다. 아차차 보안 신경을 안쓰고 구매해버려서  아직도 못쓰고 있지 뭡니까 ㅜㅜ 정말 죄송한 말씀입니다만 환불해주신다면 새로운 아이디로 가입해서 재구매하고 싶습니닷 ㅜㅜ 보안상 지금 계정에 구매기록을 남기기 시러서용!

**Developer response:** 똥쟁이님(👀!!) 소중한 응원과 코코넛 볼트를 구매해 주셔서 진심으로 감사드립니다!
별도 채널에서 안내드린 것처럼 애플 정책상 개발자가 직접 환불을 진행할 수 없는 것으로 확인되었습니다.
앞으로도 더욱 안전하고 편리한 제품으로 보답드리겠습니다. 감사합니다! 🥥✨
