Thanks for raising this issue. Seems I can't reproduce this issue with below tf config and latest tf azurerm provider. Could you provide reproduce steps and the simplest tf config that triggers this issue? Could you also try below tf config with latest tf azurerm provider to see if the issue still exists? Thanks.
