Hi, thank you for your response,
But unfortunately I am still facing the same problem,
I only have a single account associated with azure portal, which is active and allows me to access and view all my associated resources. This is the same account and login that I have always used to access Form recognizer studio, and it has been recently after the upgrade to Document Intelligent studio that I can no longer log in using the same login. But strangely I can access azure portal. I can also use the customs models trained with Form recognizer studio previously, I do it through the API. But it was when I wanted to verify something directly through Document Intelligence Studio that I noticed that I could not access.
Thanks in advance
