RM's Shopify App:

I'm having major issues with C&D constantly fixing the trading address to the wrong address, and you can't change it. It doesn't follow the default settings within the C&D account settings, and seems to be associated with the Shopify app settings for Royal Mail. For some reason those app settings does not correlate what I have setup as trading address in Shopify either.

As a result, undeliverables or returns, constantly gets sent to the address on the label - the wrong trading address resulting in constant losses. PLEASE FIX. This has been ongoing for months.

In the order processing details (before you pay) this appears under Trade name, Channel section. You can't change it.
