'No organizations found' when trying to link to Azure DevOps repository

I have previously had sites building automatically from Azure DevOps repositories, but when I try to add a new site with a link to a new Azure DevOps repository, I just get the error ’ No organizations found’. I see the same if I try to re-link existing repositories.

I’ve followed the troubleshooting steps (as I did to get this working originally) and confirmed that the OAuth setting is enabled for the organisation and that my user account is in the Project Administrators group for the projects I’m working on.

As well as the troubleshooting steps, I asked Ask Netlify, which pointed me to create a support request, which pointed me here (currently on a free account).

Has anything changed recently at Netlify or more likely at Azure DevOps which may have caused things to stop working? Could it be related to this?

I am seeing the Azure repositories again now that the admin has had a chance to add me to the Project Collection Administrators.
