WC POS seems to not be compatible - throwing error

[Valentina R]

A user is getting an E_ERROR on line 82 on the file mentioned below. Check the error here.

In woocommerce-appointments/includes/integrations/woocommerce-point-of-sale/class-wc-appointments-integration-point-of-sale.php it says that the last compatibility check was with WooCommerce Points of Sale 4.1.8.

The curent version of WC POS is 4.5.27.

[Željan Topić]

From 4.7.0, "Raise Sale" button will not be available from the calendar any more.

Paying for Appointments will work this way: 1. Add appointment through admin 2. Open POS register. 3. Load / Restrieve Sales inside the register. 4. Pick the created order/appointment. 5. Pay for the order/appointment.
