After reading this How the new ProxyAdmin will work
I was able to run the command in truffle console using the proxyAdmin as the sender
.. in truffle console
proxyAdmin = '0xF52FD...'
myContact.owner({from:proxyAdmin})
BUT still when trying to set/transfer/change the admin to another address via oz set-admin,
I'm still getting:
No contract instances that match contract MyContract are owned by this project
Is there a way to resolve this?
