I am attempting to login to a website using SSO (let's say https://account.box.com/login) using my Microsoft account. Using a plain WebView, v1803.
However, I receive the following error : "AADSTS900561: The endpoint only accepts POST requests. Received a GET request" (please see below screenshot for more details).
Edit : After investigating a little, I've noticed that when logging in to Microsoft, it does a few requests (3 or 4 POSTs) and each response tries to set cookies - could it be that the cookies cannot be set?
Would you be able to advise?
Thank you kindly.
