If you are in an out of service version, you receive the following message in LCS: 

"A quality update is not available. The product version that you're currently running is out of service. Please apply a service update to stay current with the latest features and functionality."

Even so, Proactive Quality Updates are applied, and they do not appear as scheduled in LCS. 

The users know that the PQU is going to be applied if they look at the message center, if they only look at LCS, it seems that the PQU is not going to be applied. 

It would be interesting to put some notification in LCS warning that the PQU is going to be applied or add it in upcoming updates, to avoid this type of confusion.

Thanks in advance.
