On December 9th I asked (https://success.salesforce.com/0D53A00004gqe8e) if anyone else is receiving (or have received in the past) the message, "There is currently another Publish operation taking place" when publishing in Community Builder?

The response we've received from Salesforce Support is, "this is because of the sitemap updating. They said that the sitemap updates every 24 hours effectively locking publishing until the operation is complete. As per their advise, it is either wait for the update to process then publish or publish during off peak hours, or test their changes in a sandbox and then deploy then publish once in production."

So others must be experiencing this, right?
