Thank you both for the feedback!
I have been clearing out old / disconnected clients from out ESET Protect portal, but the total seats in there seems to be lower than the license usage in the EBA portal, which is why I wanted to check.
Regarding the issue with deactivation of inactive devices not currently working, if my license is over-provisioned, but I can't remove dead clients, will I start running into problems with activations?
We are only over by 24 seats at the moment (we have a 970 seat license, and 994 in use). We will need to increase our license anyway, as being so close to the limit doesn't feel very comfortable... but I know that there's more than 24 "dead" clients out there that would bring us under usage again if they were cleared out.
Again, thanks for your quick responses and help. Have a good day!
