I got 3 orders and buyers did not give their feedback on that should i ask them to leave reviews so i can know your opinion about the work ?
It’s probably not a good idea to ask for reviews as it risks receiving a warning (especially if CS think you’re trying to manipulate the reviews/want the buyer to leave a high rating). It also might annoy the buyer.
Some people do leave feedback, some people don’t. My own is at about 70% rated orders. I don’t think it’s really anything to worry about.
