We created a few flows that work fine when associated with our BC sandbox environment. We took these, performed a Save As, and redefined the environment name in those automated trigger steps. Same company name, just a change in the environment name. There were no warnings or errors when doing so. And the changes saved just fine.
The issue is that the production flows aren't triggered at all. For example, the first step of one flow is automated for when a new sales invoice is posted. Testing this out, the flow logs are still empty. I have seen cases where a typo in the company name results in an error. Since the flow step can't retrieve data from BC. In this case, no errors. Nothing at all.
This is a premium flow, and my user account that created it and manages it has a Power Automate Premium license. Running out of ideas about things to try....
