Hi everyone,
A ex colleague created a flow but he didn't share with anyone before he left. We are trying to get ownship of the flow and we found a way to do it through Flow admin center https://admin.powerplatform.microsoft.com/
We go to resources->the environment -> the flow ->share ->add user->save
However, as we save, it gives an error "There was an error while updating the users."
My account has System Administrator access. Do I still need some extra permissions somewhere? Please help. Thanks.

Cheers
