License Delivery maintenance is expected to occur on Saturday, November 30, between 8 AM and 11 AM CET. This may cause a short 3-hours outage in which license-related tasks: license key upload, download, update, SSA validation, access to the license pool and Graphisoft ID authentication may not function properly. We apologize for any inconvenience.
