This does not directly address your question, and I'm not sure if it will work in your setup,
but just wanted to pass this along regarding switching from Dev to Prod.
There's a possibility that that method might prevent the re-ordering of tabs.
Thanks. I ended up just pasting the sheets over and not the dashboard. Then built the dashboard all over again and it is fine. The dashboard build was not lengthy. Building the separate tabs is normally the most time consuming for me. Thanks.
