SERVER ERROR⚠️⚠️⚠️ – Skin Creator: Diamond Edition Review

This app is good so far back a few months ago but a few days ago. I was about changing a skin but the connection between this app and my minecraft pc account, there's a big server error for uploading a skin of mine from this app to my account of the skin changing option page. Can you honestly please help get fixing up that issue, I will be happy for that. Thank you.
