I was curious whether anyone has seen this message before in the screenshot below. I believe the error prevents the granted API permissions showing as these are not visible, although using the below SPOnline cmdlets says otherwise).
Approve-SPOTenantServicePrincipalPermissionRequest Deny-SPOTenantServicePrincipalPermissionRequest Revoke-SPOTenantServicePrincipalPermission
I've been developing an SPFX application and have probably overfiddled by turning on/off the isDomainIsolated parameter in the config.json file and deleting the duplicate Azure App Registrations entries that occur when deleting and adding again the .sppkg file to the app catalogue.
Any help greatly appreciated, thanks.
