I find it very difficult to get aware of errors in the automated sync process:
The sync status information page displays errors from the sync logs, but if you have several accomodations with a short sync interval the list gets very long (serveral thousand entries) and there is no option to search for log entries with errors nor to sort the list according to entries in the error column.This would be a very helpful improvement in future releases.
I would even prefer an email notification in case that sync errors occur. But this might be a bigger effort.
