Hi Christoffer,
This is currently identified as a defect on Airwave side and engineering is working on it. If the license count exceeds ( No of devices added in Airwave) the threshold mentioned in AMP Setup >> General page, we are getting this message and could not "Unignore" or "Delete" the device from Ignored devices list.
As a work around you can use the below commands from Airwave CLI to un ignore these devices,
To move all the devices from ignore list to New devices list, we can use the below command,
# dbc "update ap set state = 0 where state = 3;"
To move any specific devices from ignore list to New devices list, we can use the below command,
# dbc "update ap set state = 0 where lan_mac = '<device mac>'";
Note: Replace <device mac> with actual mac of the device. Below is an example,
# dbc "update ap set state = 0 where lan_mac = '9C:1C:12:CB:5E:78'";
Let me know if you have any queries.
Thank you,
Vishnu
