I'm trying to import a contract that is deployed on the Mumbai testnet: 0xF15A2ada64A9C3C14ca11359c8F1d22B063DB2AD .
When I try to import this address ("Add contract") with Network=Mumbai I get the following error message:
"Failed to retrieve ABI automatically. The selected contract's source code is not verified. You could verify the target contract on either Etherscan or Sourcify or copy and paste the ABI manually."
The contract's source code is verified and can be obtained from PolygonScan: https://mumbai.polygonscan.com/address/0xF15A2ada64A9C3C14ca11359c8F1d22B063DB2AD
I'm using defender.openzeppelin.com .
I can't think of more details to provide, but let me know if you need more.
