Only problem with your novel is that for many months before this Roon has been telling manufacturers like KEF not to do this and that they will be stopping uncertified Roon products from working at all. Also a while before September they told them about this deadline. Seems KEF and some others chose to ignore these warnings probably because they thought they were nearly there and would get certification soon, However on testing the product Roon found problems and denied certification and KEF has not yet been able to fix these problems.
For those who think Roon has to do things to fix these problems see this.
Updates to Roon’s SDK to support new hardware are rare and of course Roon and RAAT are not updated to support new hardware or we would be getting updates very few weeks.
