Error - Oh Sheet!

I keep on getting the below error whenever I try to copy an app. Any Idea Why or what causing it.

Oh sheet!
An error occurred duplicating the app.

What’s the app you’re trying to copy?

I just tried coping from a different community post and got the same error.

We’ll fix it soon. Thank you for reporting!

This should be fixed now.

same problem! Still can’t make a copy

The app you’re trying to copy has the additional problem that the spreadsheet contains lots of formatting on empty cells which actually ends up causing the copy to time out. Do you know the author of the app? Can you get in touch with them and ask them to delete all empty rows? That’ll speed up their sheet reload a lot, as well.
