question

We've confirmed with a pic of the order screen that there is a customer attached.

Our app gets the Order and Customer with an OrderConnecter in our customer tender activity (code fragment below).

We definitely did have to add customer read permission in an app update. We had issues with this merchant in the uninstall/reinstall process but I'm relatively confident it eventually worked.

new Thread(new Runnable() {
    @Override
    public void run() {
        OrderConnector orderConnector = new OrderConnector(getApplicationContext(), CloverAccount.getAccount(TenderActivity.this), null);
        try {

            Order order = orderConnector.getOrder(mOrderId);
            List<Customer> customers = order.getCustomers();
            Logger.i("log_test", "Set CustomerInfo from " + customers.size() + " customer");

            // assign object whether or not we have an attached customer
            mTenderViewModel.CustomerInfo = new JSONObject();

            if (customers != null && customers.size() > 0) {
                try {
                    mTenderViewModel.CustomerInfo.put(Constant.KEY_MOBILE, customers.get(0).getPhoneNumbers().get(0).getPhoneNumber());
                    mTenderViewModel.CustomerInfo.put(Constant.KEY_EMAIL, customers.get(0).getEmailAddresses().get(0).getEmailAddress());
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        } catch (RemoteException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        } catch (ServiceException e) {
            e.printStackTrace();
        } catch (BindingException e) {
            e.printStackTrace();
        }
    }
}).start();
