Hi all, I have a hybrid network with some DECO X50 and 2 DECO X50 Outdoor (>1000m² to cover)

It has been working OK for the past few months, but I'm experiencing some ISP reliability issues lately (cable-based, they are working on the network - fiber etc - leading to frequent outages). I'm using my connection professionally so having a reliable connection is very important to me. There is no alternative provider or fiber in my area yet.

For that reason I wanted to add a DECO X50-5G to my set-up to add 5G backup in case my main connectivity goes down (5G has just become available here a couple of days ago)

I have purchased the DECO X50-5G, and an extra 5G SIM subscription, and added it to my set-up.

The X50-5G is added as an extra Deco to my set-up, but to my surprise I have no 'internet backup' option in my Advanced menu.

It seems like I have to install a new (unfinished) firmware to get the feature.
Which - even if I wanted to do that - does not work since the web interface does not work (I the firmware upgrade section I cannot select a Device Model in the dropdown - the dropdown does not present any options - hence I'm stuck).

I thought about moving the X50-5G to as Main Deco, however then I seem to have to deactivate EasyMesh since not supported on the X50-5G. Not sure what the implication of that is.

It sounds a bit like the 5G backup has been marketed as a feature prematurely, leading me to the conclusion I would have to return the X50-5G since it does not provide the functionality I wanted. Definitely given the price it costs.

Does anybody see any alternative solutions or some advice to still get it working?
