I have 60F and two AP one is connected through LAN and one is connected through MESH. Mesh AP (Leaf AP) when disconnect from ROOT AP it is not reconnect automatically. But when we reboot Mesh AP (Leaf AP) it's reconnect again. Fortigate 60F firmware is 6.2.5 build 1142 and FortiAP 431F firmware is 6.4 build 163. This issue happened from beginning.

Hi @arnab 
You can try upgrade your devices as per compatibility matrix and see if it solves your issue. 
Perhaps  you can just bring the interface up and down when this issue happens, maybe it eliminates the need for reboot.
