I got in touch with the API Support team on 21st August, as soon as I realised there was a problem but apparently 2 weeks after the change was inmplemented with no notification. Tana's response suggests that they were blind-sided by this too so not much help there. It is clear they have little more knowledge about this change than us add-on developers.
Talk about which browser one uses displays a complete ignorance of the fact that Windows applications do not use external browser apps to communicate over the internet. They can either use a browser control in a form or converse via GETs and POSTs etc.
What has changed is the format/structure of the response. The specification of the change to that response needed to be published clearly many months before the change-over. Several weeks after this change we are finally getting an admission that the json response we had all been relying on for over a decade is not being returned.
Also I completely fail to see why the response should trigger the launching of Edge. That is completely unnecessary and a hideous distraction.
