I have also had the same problem today when import from Sketch into Principle!
Have tired re-installing both applications and no luck. Just seemed to happen today.

I get the same Import Failure and message.

Hope this can get fixed.


Exact same thing is happening to me too! I can’t import the whole file or selected artboards.

Principle 5.11 is now available with import support for Sketch 66.
