How have you set your due date in the action? If you observe the approval record what is the due date value? What does your flow look like? Is the ask for approval step in completed state?

For example reject in 1 minute from ritm opened at:

@lauri457 @Tejas Adhalrao , here is my case it is very urgent I am requesting approval for RITM  for 3 groups equally and the there is a time out I need to proceed with the time out condition so in my case when 
If all required groups approve → RITM = Approved
2️⃣ If at least one group rejects → RITM = Rejected
3️⃣ If due date passes (even if 1 or 2 approved) → RITM = Timed Out

so for the due date is 2 min from the RITM  created

What happens with the flow execution? Does the flow progress past the ask for approval? Does it error? Does it hang? What is the due date on the approvals? This is what matters, could be your schedule is not running currently so your due date is way in the future

@lauri457 , the flow holds waits the approval Flow action it is working in rejection and approval case but when we come to time out it did not consider my time out due date
