Hi,

After upgrading WLC-9800  from 17.6.5 to 17.9.4 license showing not in use. When the WLC was in 17.6.5 we can see the Essential license, but when we upgraded to 17.9.4 there was no license showing though smart license is enabled.

though it showing option for Essential license in change license wireless level but not in use. Rebooted after version upgrade but still not working.

After 8/10 hours the licences appeared automatically. It seems it has taken sometimes to sync.
