RC Construction Vehicle Store review for MatrixRates Import/Export

Sorry to hear you had a frustrating experience. After reviewing your account, the import failures were caused by an invalid API session, which can occur if the app is installed and uninstalled multiple times in a short period. This prevented Shopify delivery zones and methods from updating correctly. The issue is recoverable and would be resolved on reinstall. We reached out after the app was uninstalled to help, but didn’t receive a response. If you’re open to trying again, I’m happy to personally assist with setup and will also apply a free month to your plan for the inconvenience. Please feel free to reply directly to the support email.
