Used for the first time and they do not have an option to leave a tip. I have contacted customer service 3 times regarding this issue, including screenshot so they can see. They simply send out the same instructions over and over. Was able to rate the order, but not leave a tip. Beyond ridiculous 🙄 This isn't mentioning that the app and website aren't user-friendly, as evidenced by the ability to rate my order, but not to tip the shopper. Wondering how much this poor shopper is losing out.
