As buyers, how to complete an order and leave feedback later?

[michaelbui2812]

I purchased an order and the seller committed to deliver an initial result in 1 day and continue working on the order in next 30 days.

After 1 day, he did send me the initial result and marked the order as “Delivered” then asked me to leave him a positive feedback

From Fiverr support pages:

• http://support.fiverr.com/hc/en-us/articles/204361333-Providing-Feedback
  and
• http://support.fiverr.com/hc/en-us/articles/201504276-Rating-your-Order
  I do know that:
• An order will be automatically marked as “Completed”
• A buyer and leave a feedback for the oder within 30 days after it’s marked “Delivered” or “Completed”
• Once a feedback is provided, it can be changed within 3 days

My question is: What should I do to be able to leave feedback within next 30 days?
Can I just let the order auto-complete and have 30 days to leave feedback? Is that leaving feedback still possible after the order is auto-completed?

Thanks everybody 🙂
