C# App has worked for years (MYOB.AccountRight.SDK.dll) Upgrade forced, now broken
Using 2019 version for years, MYOB forced upgrade to current model. Was working OK for a week but now throws 404 error. Authentication passes OK (401 not thrown) so underlying connectivity correct but any querying of invoice pages or anything else throws 404.
Any suggestions before I do a deep dive ?
