Any chance to get this fixed? This .afpub was created 2 days ago, saved and closed. Today it refuses to open with the error "File is already open in another application". … No chance, even if I close every other application + relaunch APub:
As a possible workaround I copied this .afpub in the macOS Finder. But now "The file type is not supported."
How does this work? Where can I fix this? It does not seem to be caused by a leftover in my APub library folder – but where else?
I one of you able to open this file and save it with Save As with a different name + upload again?
