I was thinking there was another comment from WT about it basically being about software/firmware, but couldn’t find it here. Turned out it was a response they sent me via the app we use for testing.

I asked about where the problems remaining were. Essentially asking it if was down to things like cleaning up some swap issues, connection issues, etc, rather than hardware. The key part of their response was:

That’s about right

And they went on to talk about the software/firmware challenges. But nothing about hardware. This was a month ago so newer than the quote I gave before.
