FortiOS 7.2.8 restricts the automatic firmware upgrades to the FortiGate
Automatic firmware upgrades update the FortiGate and any connected FortiSwitch, FortiAP, and FortiExtender devices. This caused issues with FortiAPs going into a boot loop due to reboot timing. FortiOS 7.2.8 introduces a temporary fix: restrict the automatic firmware upgrades to the FortiGate only.
