There are various places in the app where you can access the "Free food" section. In the menu, there's a regular "Free food" option and a larger "Get £10 off your next order" option with an image at the bottom.
There are also "Get £10 off your order" banners in the main feed on the homepage, which is what we opt to use here.
Free delivery banner on home page
There's a "Free delivery on orders of $50+" banner on the home page that wasn't there last week.
Invite buttons A/B test
The Invite buttons are still being tested it seems. This week they are the full width buttons with small icons and the options are Messages, Mail, and More Options.
The "Free food" page includes an image, a large section showing you your referral code clearly, a description of what you get for referrals, and invite buttons.
Selecting the "Mail" option brings up pre-populated email ready to send. Unlike last week, there's no in-app process for adding contacts to send to. You just have to popular the "To" field in the email as you normally would when sending an email.
Once the invites are sent, the email popup closes and you're back in the Uber Eats app in the "Free food" section. There's no success message/feedback.
