Failing to update App Settings on Azure Function When MSI is Enabled

I have a function with Managed Service identity enabled. When I try to update app settings via Azure portal I am getting following error.

Failed to update web app settings: ["{\"error\":{\"code\":\"CannotRemoveResourceIdentity\",\"message\":\"Resource identity of type 'SystemAssigned' already exists on resource and can not be removed.\"}}"]

I have tried disabling MSI and then changing the App settings, but it failed to update with same error.

Is this a known issue with MSI and Azure Functions?

Alternatively as a work-around you can go to https://resources.azure.com.

You can also find it in functions from Platform features -> Resource Explorer.

Find your function, and go to config -> appsettings. You should be able to update them from here.

I solved my problem with updating the SSL certificate on a Web App in this way.
