Hi everybody,
Adobe released InDesign CC two days ago and we made some quick tests to see whether App Studio works with it.
As a starter you can install the plug-in/extension just fine. Remember to use Adobe's Extension Manager CC, as the Extension Manager CS6 will of course only install extensions for InDesign CS6.
Bad news are that unfortunately currently you cannot log-in using the App Studio Exporter panel, as something is different in InDesign CC.
Good news are that we have analyzed the problem and found the cause.
We are currently working on a solution to fix this. We'll let you know once it's ready, it shouldn't be long.
Thank you for your understanding.
Regards
Matthias
