Hold off on Revit 2016 Update Release 4

If you are using Revit 2016 and Collaboration for Revit (C4R) then you'll want to hold off installing the most recent update. Kyle shared the following in a post at RFO.

We have identified a compatibility issue with the latest Revit 2016 UR4 update, which is causing degraded Sync with Central (SWC) reliability for those that installed it. We have confirmed this issue internally, and are working to resolve the issue within our services.

Teams are advised to defer installing the latest Revit 2016 UR4 until we have resolved the matter on the Cloud Worksharing service. We apologize for the disruption this may be causing, and are urgently working to resolve the matter.
