Terraform Version

Affected Resource(s)/Data Source(s)

azurerm_app_service_managed_certificate

Terraform Configuration Files

resource "azurerm_app_service_managed_certificate" "cert" {
  {...}
  tags     = merge(local.tags, var.tags)
}

# we are using the above alongside azurerm_linux_web_app and azurerm_windows_web_app

Debug Output/Panic Output

resource "azurerm_app_service_managed_certificate" "cert" {
  id = "..."
  ~ tags                       = {
      + "..." = "..."
    }
    # (8 unchanged attributes hidden)
}

Expected Behaviour

Tags should be saved to the managed certificate

Actual Behaviour

Certificate resource tags are not saved on Azure.
Re-running terraform apply causes an update-in-place, with tags being modified on each run, but not persisted.

Steps to Reproduce

terraform apply
