@dchakro That shortcut was made on ios 13+, which ScPL does not support. Even if it did import, lots of the actions would be broken. I would improve the error message, but unfortunately since the project has been inactive for so long, I can no longer build the editor so making changes to it would require significant effort to upgrade stuff
