Processing of Sketch Cloud files by Plant can lead to inconsistency of information contained in both Plant versions and in Sketch Cloud, as well as cause false design conflicts.
To avoid this, our team decided not to support such files yet. We will continue to monitor the development of Sketch Cloud in order to offer a solution in the future that will not contain problems mentioned above.
At this point, in order to continue working with Plant and create a project use the following step:
In Sketch go to File > Make Local Copy... then create a project in Plant.
