Every hour, during a couple of minutes, I receive this message repeatedly. I get similar messages for 'full' and 'object' for that same user.
The user related to the message is the service account that I use to run my Qlik Sense services.
The command related to the messages is always the same: 'add app privileges'.
This user does not have a license assigned, as I don't imagine it needs one and I don't really have any to spare (if Qlik services need to work in hub or other, then Qlik should make sure this is possible without consuming my highly paid licenses).
The timing seems to coincide with the reload tasks for Operations Monitor and License Monitor.
So I'm guessing this is a configuration error or an inherited situation (Installation has been updated numerous times starting with a version 2 and now at November 2018).
