During creation of art, we verify that the signedData, i.e., credId and uri supplied is validated by the phiSignerAddress before providing the signature. This signature is then verified onchain as seen in the function below. The issue is that if the phiSignerAddress is updated through the setter, the latest signatures issues would cause a revert during art creation since Line 623 would evaluate to true.
Although this works as intended and users can simply take new signatures from the new phiSignerAddress, it is an edge case worth looking into to avoid unnecessary latest signature failures when a phiSignerAddress is changed. 
Before supplying signatures from the frontend, ensure the phiSignerAddress has not been updated onchain. If updated, supply signature through the frontend provided the new phiSignerAddress is configured.
