Great support.

Here is some feedback.
I noticed that this firmware update affected remote reboot from outside. When you try to reboot it will disconnect the remote session and it will take very long time before it initiate the reboot and comes back to the remote capability again. It might take 30 minutes or so.
I have tested the reboot from inside the LAN and it is fast, the only issue is when you are remoting via the internet.

When I revert back to 1.26.1 the remote reboot is restored and immediate. So this is only 1.27 (1) issue.
