Hi @kmason,
I haven’t seen such an issue so far. Could you show me a screenshot of your flow configuration?
Please make sure you don’t have another flow with the same approval action to the same approver.
I made a simple test and I didn’t get the issue you mentioned. If possible, please try to recreate the flow to see if the first approver will still get two emails.
Please feel free reply if you are still having the issue.
Best regards,
Mabel Mao
