Wix Restaurants (new): Managing Orders in the Wix Owner App

Hi, im working on a website for a bakery and have a few questions. All questions are about wix restaurants in the Wix Owner App (not on desktop!):

Editing orders in the wix owners app (by editing i mean adding new menu items to the order, changing quantity, removing existing items from the order)
Can i edit the order i received from the customer in my wix owner app? i cant seem to find it. i can cancel the order, but i can not add or delete items from the existing order. i can do it on desktop. but its important to do it on the app.

Adding extra fee and marking the order as paid - results in “partially paid”
When I collect the payment, if I have added an extra fee - then if I click collect the payment it will always stay “partially paid”. On desktop I can add a check mark V to collect extra fee, but here I cant.

this one looks more like a bug to me actually. For example: the client ordered something for 100 USD, i added there a service fee through order editing - 10 USD. Now the client has to pay $110. On desktop i can send both 100 or 110 options. On Mobile it seems like only 100 - and the order is always “partially paid” even if i mark it as paid.

Creating new orders on the go
How do I create a new order on the wix owner app? There is a way only to create a new invoice, but then it suddenly asks me for products and services. And I have menu items. So what do I do?

Creating Proposals and Invoices
There is an option on the menu “Create Invoice” and “Create a Proposal” BUT
Proposals and invoices are not linked to the Menu? Again talking about specifically wix owner app - do we need to create a list of products similar to menu items in order for proposals and invoices to start working?

Product:
Wix editor + wix restaurants (new), wix restaurants old, wix restaurants menu (new) and old.

What are you trying to achieve:
the key to me is managing the bakery on the go - when the order is received it should be possible to add items to the existing order from the wix owner app. Also it should be possible to create a new order from the wix owner app.
