This is version 2.0.0 of Fonto Connectors! Fonto Connectors is, as you can read in the product guide, a standard way to connect the Fonto Editor to your CMS/DMS via CMIS/WebDAV or connect to your cloud provider like Google Drive or Microsoft OneDrive.
Please see the getting started guide for more information.
OneDrive: Trying to create a file in a shared directory causes an error, because the user has no access.
Google Drive: Opening large maps causes errors because of the limited amount of requests Google allows.
