Unusable After Last Update

I have been using for years and loved this app so much until now. Suddenly this week, after the most recent October update, the images fail to enlarge. After taking a very long time to upload to 100%, it then gives error and says "Failed" instead of proceeding to enlarge the image. I click "retry" but it keeps giving same error. Even after closing app out and starting over. Have been trying for over 3 hours with no success. Please bring old version back!!!!!!🙏

완전 강추추

예전부터 꾸준히 쓰던 유저입니다 ! 옛날에는 번역이 안된 영어 상태라 불편하긴 했지만 그래도 화질이 좋아지니까 기분이 좋고 만족스러워서 그대로 쓰고 있었는데 번역이 되고 이제는 완전 세련되게 업데이트를 하니까 완전 만족해요 !! 한달에 20장(?) 정도 밖에는 못하지만 가성비로 치면 진짜 강추 !!

감사합니다 최고입니다 ㅠㅠ

개발자님 사랑해요 ㅠㅠ❤️ 진짜 앱 너무너무 좋아요 ㅠㅠ 화질 좋아서 덕분에 유용하게 쓰고 있습니다! 개발자님 복 받으세용❤️ㅠㅠ

Issue with downloading

I love this app sm, been using it for a long time now until I ran into an issue where the app doesn’t finish enlarging the image 💔 I even uninstalled and reinstalled to see if it helped but it didn’t do anything, it just gets stuck. I hope this bug gets resolved soon.
