I had it working for 3 of my 4 applications briefly and have been testing, as responsible developers do before deploying new versions. Today I find it is not working again so took a look at what came back from the request and found that far from it being a response providing the necessary oauth token and possibly a few other pertinent data items I had got back a page or so of a html ranting on about how wonderful MYOB was for small developers. If someone thinks that sort of thing is appropriate to shove in the faces of the clients of add-on developers whenever they install the add-on software on a new PC or for a new employee they should think again.
It looks as though someone is of the impression that this authorization only gets applied when a fresh new developer starts up a new ad-hoc app for in-house use. I suspect that the perpetrators are probably unaware of how this is used and driven by some marketing/fashion motivation, quite unaware of any change management process.
Myob is losing ground to Xero partly because Xero has a better range of add-ons. Breaking the existing add-ons is a long way from how to fix that.
Could you please escalate this. It cannot just be fixed by linking to other developers discussions as to how to get round the problem. It is simply not acceptable to have add-ons being broken by ad-hoc changes without notice. The change management process should involve planning and notification well in advance, similar to the way it was managed for the upgrade to use TLS1.2 back in 2017, when we were given ample notice to enable us to prepare new releases.
