@marcus67 Ah yes, I see your email but have not yet had time to investigate.
As soon as I know why it happens, the fix is probably not far away.

You will hear from me.

@mikael I am the developer of Working Copy.

I will be looking at this delay you experience when doing x-callback-url commands. I have heard about this before and it should not be that way.

When Working Copy is put in the background it will only be allowed to run for a little while before being put to sleep by iOS and then the WebDAV server shuts down as well. Could this be what you experience?
