From Cloud Instance B, I exported my personal space of my user there using CSV.
In Cloud Instance A (where I have full admin rights) I imported that ZIP and did the macro check, all good. In Confluence Space management settings (/wiki/admin/space-management), I see that this is a personal space with the ~XXXXXX identifier from instance B. No such user exists on instance A obviously.
When I click "Recover admin permission", it gives me the message: "Admin permission has been recovered for the selected space.". On page reload, it looks as before with the same button. I cannot access that space with my admin user.
How can I fix that so I have access to that space?
