PLEASE NOTE: This is a known issue on which we are working with our Engineering Team internally. And this issue is expected to be fixed in the upcoming Unleashed version 200.14 software release and the App Release.
Also please note, the 18.104.22.168.199 Unleashed version is released on 6/28/2023 only for the Web Unleashed System,and it has the fix for the unleashed.ruckuswireless.com DNS issue with the iOS device.
