Power Platform Community Forum Thread Details

I created a Powerapp around a year ago with an approval flow that sends to a manager for approval which has been working fine. However in the last 2 months or so the flow has stopped working and approvals are not being sent through to anyone even though no changes have been made to the original app, or the flow itself. When checking my approvals tab on Teams I can see that the 'sent to' column is empty as if nothing was submitted in the app (Though this should just break the flow as the value would be empty). I have tried to add a static value into the flow so that the approval just comes through to my email address, however it still has the same outcome with the 'sent to' in approvals being empty. Have Microsoft changed the way approvals work or is this a bug?
