@WireIkon,
Auto reboots for mesh are not common, as it forces each node to have to reconnect and reconfigure the network, for wired backhaul this is no problem. However, wireless nodes that don't have the best connection may have difficulty rebuilding the network and their connections, as all clients connected to the network will begin to roam.
Saying that our development team has actually been adding this to applicable models as it is developed. The first model to receive the function was the M5, and it was only a few months ago. With how quick the firmware for models has been developing over the last few months, it may come to other models soon.
I will try to reach out and learn more information regarding the feature and when it may/if it will release for other models soon.
For now, I would recommend visiting the feature requests section of our forum, so that your feedback can be properly tracked and passed to the correct teams.
