Thanks everyone for the patience, and for your questions on timings.
I’ve asked the teams involved for an update just today, and as soon as I have something to share, I will do so. We are globally distributed so I can’t rock up to someone’s desk to pin them down for an answer.
To address one of the comments on this thread - there’s no deliberate effort here to push anyone to an alternative. Something broke and needs to be fixed, and as I understand it the work to resolve it is ongoing (if not something I can tell you about in more detail as I type this, or I would!).
