Error message: "Another User is Pushing"

Issue:

• Synchronization was not able to update the Imodel with processed changes.  

Cause:

• This indicates that another user is trying to update an iModel with new information from the same file. This is most likely to be because both the cloud-based synchronization and the iTwin Synchronizer Client are being used on the same iModel at the same time. This is not good practice and will most likely lead to errors.
• Another possibility is that the cloud-based synchronization is trying to run two different connections at the same time which are competing for the same iModel. This is most likely when there are long running connections taking longer to complete than the time between scheduled synchronizations, and is not an intended method of operation.

Solution:

• Please check if multiple connections are running at the same time and cancel a concurrent job. 
• Contact Bentley support if this is happening regularly
