@shaun-h I have done my multiple tests with the same empty page since the beginning. But, just to be sure, i've opened a new one.. No json error anymore.. I don't know why.. Maybe something hidden somewhere.. Your
modification for the tagid has solved the update process. Everything is ok now ! A big thank you for your help !
Did you try to contact the author of the original workflow ? Maybe you can upload your "revision". This will probably help other people even if there is modifications in the near future on the "Ghost" side.
Now, I'm just waiting for the next update of Editorial who, I hope, solved the issue with the location on iOS 9. (That's why I use pythonista to get the location information).
Thanks !
