Workfront and other Adobe tools unification - migration to cloud affected our document sharing

Hi All, 

I am curious to see if any of us here have moved/ migrated WF to cloud?

when i say that we would had our WF link https://<companyname>.my.workfront.com

and the new cloud link will redirect to open WF with new URL starts with https://experience.adobe.com

While this was a great release and as creative operation lead this was a great news for us to ensure we don't multi login our product, but having one time and switching between was a great unification. however, as this was released and within couple of hours we realised the document links to the project shared with other user who have to act on the document to review (yes, the user has manage access to project, so its not access issue) cannot open any document. Neither can I open document with experience cloud WF document link as an admin. 

I am curious to see if any of us have encountered this issue? and did you hear any solution for the same. 

Solution from support now to our issue - the production instance is pulled out of unification and asked us to use WF as previous with old link. 

Note: Fetching document link or project access is not an issue. Document links are fetched as usual and we share document links within our group who are assigned to the task and have access to projects.  

Enclosing errors that we see.
