Models missing from Team Server Model Explorer

We just upgraded to the new version of Team Server 2017.  Our Project folders are being displayed in the Model Explorer but none of the models are available.  According to all the documentation the synchronization process is automatic between the repository and the reporting (portal) database but I am not sure that is occurring.  I tried to find a way to force synchronization but without success.  I am in the Admin account so permissions should not be a problem.  Has anyone else seen this problem?
