Hi @Likenanadid, thanks for your post! At the moment, the system is setup so that phone numbers are always required for pickup and delivery. This is to make sure that you can easily contact the customers for pickup & delivery orders and that they themselves can track their orders like with other delivery services.
However, customer can reply STOP to opt out of receiving any future text messages relating to their order. They will see this message at checkout when providing their details as well.
When you tick the box Make phone number optional, this would only allow customer to opt out of providing a phone number for other fulfilment method like Shipping and Self-Serve Ordering.
