We have a Portal to ArcGIS Online collaboration setup (Send and Receive); however, we've noticed that some items in Portal are not syncing properly to ArcGIS Online. Looking through the log files it seems like these datasets "succeed" in their sync process; however the # of features between the Portal Item and the AGOL Item are different.
Does AGOL need a few hours or days to reindex itself to find these new features? If so, how long before they should show up?
