Wow, I cannot believe how obscured and poorly communicated the Esri Hub -> Workspaces transition has gone. I work with a small org that has used the previous version of Hub since 2021, having successfully transitioned our website to it. Fantastic at the time.
I managed to fumbled through the poor documentation on how to enable it and then begin migrating content to be managed in each workspace, but even as a 30 year veteran of webGIS it took me a while to do with a number of mistakes.
Since the Feb 25th upgrade, we're now informed that our Workspaces have been 'updated' and now we are unable to have multiple editors of a site; no clue on how to get around this, let alone it BEING COMMUNICATED AHEAD OF THE UPGRADE. Esri, you need to do better - telling your clients of what's changed AFTER is less effective than telling them AHEAD of time.
Are other Esri clients just gobsmacked at how poorly Workspaces has been rolled out? Let alone, it's not an improved pattern for managing content. In my view, one of the worst Esri implementations ever.
There is a question in all of this - how many other clients have faced challenges like we have? How do we enable multiple editors for a single Hub site/Workspace?
