Hiya @Chilternphil, thanks for getting back to me. I am sorry for the delay in your firmware update being picked up.
I've had a check of the request I sent and it hasn't yet been picked up by the team, checking other requests it does look like the team are quite behind with requests but I'm sure they will get this picked up as soon as they can.
I'm really sorry for the inconvenience caused in the meantime.

Many thanks. Noted this afternoon that the software update date had changed to today though router still reported old version. Thought I would restart the router and it now shows its at the latest version. Now to see if house network is more reliable as we use all the devices.
