I'm getting "not authorized" to a tutorial page in EMA(https://developers.thomsonreuters.com/elektron/elektron-sdk-java/learning?content=8738&type=learning_material_item).
Below link is for the multiple mechanisms link present in the above page.
The links in the tutorials needed to be updated/corrected to reflect the updated documentation. Give it a try within the tutorial and let us know if this has resolved what you found. Certainly let us know if you detect any other issues.
The link seems incorrect, so it returns 404 error.
