zharkan I really want to help you. But I don’t understand what’s happening. Why aren’t you using the flexible times?
Admin Panel -> Restaurant -> Settings -> Opening Hours
Now, if you want the "Delivery in 15 min"
marked by default when a customer browses your menu. That’s possible to do.
Are you in the slack group? if so, you can contact me (Mauricio Lattke) so I can help you with this.
