Shipment tracking does not work

The plugin does not work with woocommerce shipment tracking and I do not think it is fair that you have to pay for an Aftership subscription just to be able to process tik tok orders from woocommerce, surely this plugin should be stand alone since you have to pay a subscription. We have been trying to get support on this issue for days but Matt is impossible to get hold of and once he finally replies to our message and then we reply back the message is then picked up by someone else who has no idea how to help us. How do we get dedicated support please??
