Anyone here ready to give us tips on a product and launch strategy?

We are launching a delivery superapp in Africa and we need a review on the product and market launch strategy. So basically, the app makes delivery faster by allowing you to shop from local merchants close to you, these orders are picked up by our riders and delivered to the customer. Here's the link to the app Beta (few bugs tho) https://play.google.com/store/ap... *What do you think about Billie? *Any tip for a nice launch strategy?
