Approvers who receive an approval request through our Start and Wait for an Approval workflows continue to receive duplicate email notifications if they leave those requests pending for more than a day. The duplicate emails come in twice a day for each pending request, at the same two times every day, until the approver submits a response. The flow seems to be otherwise functioning correctly, the Start and Wait for an Approval action is not inside an Apply to Each loop, and there is no indication on the back end why this would be happening.
This thread from 2020 calls the duplicate notifications a known bug, but surely it wouldn't still be happening? Is anyone else experiencing this? https://powerusers.microsoft.com/t5/Using-Flows/Approval-Flow-sends-approval-email-daily-to-Approvers/m-p/780043#M19769
