Hi DarrenOC.
First of all, thank you for your support.
Yes, I did indeed save the configuration. I also doubted that and to clarify, I configured all the parameters again, but the problem occurs when adding the APs to the Network. At that moment, many of the options disappear and only the Network-Wide, Assurance, Wireless and Organization options are left. Then the "Security & SD-WAN" option is lost, which is where I have created the DHCP and the VLANs.
