After creating a xsuaa instance with common name (like myxsuaa-1234), I've got the following error while updating it with the security json: "Cannot change AppId with update."
We don't have any app with this kind of name (and yes I can see all Spaces/Org). So I tried to update it with this name
and it works !
So now, I'm concerned about the ability for anyone to update MY xsuaa service instance as long as they found its name.
But with a very complicated name there is no conflict anymore !
We are using a CPEA pricing and are on eu10. I've not experience this issue in another global account, also eu10 but with subscription pricing.
Please give me your thoughts on this point. Thanks
