ShipStation does not work wtih X-Cart 188.8.131.52. ShipStation is not willing to upgrade their module to be compatible with X-Cart 184.108.40.206, even though I am a paying customer for their service. ShipStation is unable to transmit tracking information back to X-Cart after creating the shipping label. As a result, tracking information has to now be manually copied and pasted back into each X-Cart order. Not happy at all with ShipStation.
